You might be reading into this more than is there. It's not so much that things are fluid as it is that they are undefined. There is no clear, consistent way for a member of the Fedora or CentOS communities, who create something great, to have that thing make its way into an update of an existing RHEL major release.

Man, it breaks my heart when I read things like this. There might be some historic truth to the above, but it doesn't have to be the future. The objective I mentioned near the end of the talk has been posted, but not yet voted on: https://fedoraproject.org/wiki/User:Pfrields/Lifecycle_Objective The beauty of community is that it can grow and shift according to the needs of its members. To me it looks like the lifecycle objective may be a partial answer to how Fedora, RHEL, and CentOS communities can reach a state of fluidity, a virtuous cycle. The thing that makes it the most likely to succeed is if members of the Fedora, RHEL, and CentOS communities work on it together.

[CentOS] systemd automount of cifs share hangs
Running latest CentOS 7.5. Since I found out about automount unit files I've had mixed results using them to mount shares from my NAS. Lately they seem to hang if I touch the mount point, but I can start the mount unit without problems. I had it working months ago, so I'm thinking something changed in the systemd updates. For each mount point, I have two files in /etc/systemd/system named with the path of the mount point and with extensions .automount and .mount, following the systemd documentation. For example, srv-dav-name1.mount and srv-dav-name1.automount to mount a NAS share to /srv/dav/name1. I can issue "systemctl start srv-dav-name1.mount" and the mount completes instantly. But if I start the automount unit and ls the mount point, the shell hangs and eventually, a long time later (I haven't timed it, maybe an hour), I eventually get a prompt again. Control-C won't interrupt it. I can still ssh in and get another session so it's just the process that's accessing the mount point that hangs. Any suggestions on how I can debug this? I'm still new to finding the right log files. /var/log/messages doesn't show any errors like timeouts. ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

Having worked with the init systems in a bunch of different distros, I really *loved* having to write a different SysV init script for debian and RHEL, using different functions and different styles. Also, don't forget to actually package the Red Hat init scripts as /etc/rc.d/init.d/, because /etc/init.d is a symlink, while on debian it is the actual location, and if you weren't careful, your package would create an /etc/init.d directory and suddenly it's not even found by the init system. The first time I had to look at SysV init scripts on a Debian/Ubuntu box my eyes bled; if systemd had begun from that ecosystem I definitely would have understood its formation a bit more. But on Red Hat-derived distros, an initscript for a basic daemon is pretty simple and mostly boilerplate: copy/paste the sample file, maybe decide what you want to make tweakable in /etc/sysconfig/, then (if desired) build an RPM according to best practices. Virtually everything you might need that isn't provided by the 'functions' file is going to be your own custom logic for your own daemon, and it turns out that that usually doesn't change in a systemd landscape, resulting in a lot of workarounds, wrappers, and shell bits in unit files which would probably be more predictably understood in a single shell script to begin with. Building a single init script that works across ALL Linux distributions (and other unices) is indeed painful and ugly, so if a vendor wanted to make a declarative config file and wash their hands of, that's understandable. But the same goes for an xinetd.conf snippet, or any other service manager of the same ilk. And making a boilerplate /Red Hat-specific /init script is trivial. Heck, there was even an argument about which shell they're run with. And it was always fun when shell bugs cropped up in init scripts. A vendor writes an init script using bash features that aren't in another distro, but it still uses the #!/bin/sh shebang so you get really weird and difficult-to-diagnose startup errors. That's a larger *nix issue. As a proponent of dash on EL systems, I definitely think ensuring bashisms are called out and that /bin/sh means /bin/sh is probably a Good Thing. And heaven forbid you actually want to *SEE* any shell errors. Nothing is ever captured in any logs, you have to be physically looking at a console (be it a glass terminal or serial line) to capture the error. The /sbin/service command is just a shell script.

I think think some of the opposition to "switching back" misses the point. IMO there's nothing particularly wrong with systemd as a service manager, so folks wanting to use it as /just/ that (which accounts for the bulk of what SysV-style init scripts from vendors do) could still use it if they wanted. Initscripts work fine for traditional C unix daemons, but lots of other ecosystems (looking at java) are better served with other management systems.

As we can see from the repeated attempts to get a reliable in-place upgrade process working, the community doesn’t seem to have much interest in the idea: https://lists.centos.org/pipermail/centos/2018-October/170379.html I believe this is because in-place upgrade is antithetical to the idea of a “stable” Linux distro in the first place. Once something’s configured and running, you just want it to keep doing so. In my world, OS upgrades are generally paired with new hardware or VMs. I did just this on an Ubuntu VM recently, which does have an in-place upgrade system. I’d been ignoring its motd offers of upgrade for years, on purpose, and only upgraded it from 14.04 LTS to 18.04 LTS when I needed to rebuild the VM anyway. That’s why I was on an LTS release in the first place: to give me the years of stability that let me batch the changes up into a single big-bang upgrade. CentOS is even better in this regard, with version lifetimes up around 10 years, rather than 5 for Ubuntu LTS. One of the reasons I chose to upgrade it recently was because Ubuntu 14.04 is about to fall out of support, so it was time to move. I believe a lot of the antipathy toward systemd is that people want “LTS” to be forever. That’s not going to happen until the rest of the world stops changing. That would be a very sad thing: it’s basically a wish for stagnation. If upgrading via separate hardware or a new VM is difficult, it calls into question the usefulness of your backup and restore strategy. Another advantage of this style of upgrade is that you have the prior box online and ready to fall back to if the manual upgrade fails. If an in-place upgrade fails, you’ve just lost the primary. ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

Oh, and as for 'grokkable' shell scripts used by init, they bear only a passing resemblance between distros, they even differed between releases of the same distro, making it so you had to learn a different weird init system for each distro. Heck, there was even an argument about which shell they're run with. And it was always fun when shell bugs cropped up in init scripts.

And heaven forbid you actually want to *SEE* any shell errors. Nothing is ever captured in any logs, you have to be physically looking at a console (be it a glass terminal or serial line) to capture the error. So, yes, people starting to use systemd won't know about having to do that. They're also not custom-crafting Modelines in their XF86Config file for a monitor that uses weird undocumented, non-VESA parameters, nor are they trying to track down the right interrupt to run their network card so it doesn't interfere with their sound card. I'm sure we could create a whole book of all the annoyances with older Linuxes that have been largely solved. I don't see systemd as the end-all, be-all init system, I just think it's heading in a good direction. Its important to provide feedback like people have on this list, although people in the CentOS community really ought to provide feedback to the upstream communities. Here's a good example for me: In other systemd-based distros, they've got the systemd --user enabled (RHEL/CentOS have it patched out). This breaks a lot of our use case because the systemd developers don't think that different sessions of the same user are distinct, so they want to use systemd --user to manage user processes. This breaks if you use session-based authentication services like Kerberos. systemd --user tries to start up processes outside of your PAM session, so it won't have access to your kerberos tickets. And of course, Gnome Terminal now uses a gnome-terminal-server process to be the parent of all terminal sessions, started by systemd (as your user, on behalf of PID1). So you log in, start up a terminal, and it doesn't have any Kerberos tickets. Now, what happens if you happen to use an NFS v4 volume for $HOME, which uses Kerberos 5 for authentication? Now not only does your terminal not have tickets, but IT CAN'T EVEN REACH $HOME. And of course, systemd --user wants to read and write files in $HOME, so the whole thing is broken. What do the systemd developers say? They want it so anyone who becomes your $USER should just automatically have access to your Kerberos ticket cache, so systemd can work. This is actually breaking from the way Kerberos has worked for decades. And it seems that the systemd developers have just decided that their way is better. But I'm going to keep pushing back. -- Jonathan Billings ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

Hi, A lot was already said but let me underline a few things from my personal point of view: - the upgrade path from EL6 to EL7 is completely broken. That's certainly a good thing for upstream, because they can sell even more support and training. I don't blame them for trying to make money, I just say from the technical point of view it's not the best solution. For home users it doesn't hurt too much but for the enterprise market it's bad. Migrating complex systems is a huge amount of work and takes a lot of time and manpower. In the end it means higher costs. - the migration to systemd is not really finished carefully in EL7. Just look into upstream's Bugzilla and see how many issues still exist and will probably not be fixed. I show you a simple example: we happen not mount some NFS filesystems on servers like this in /etc/fstab: ftp:/var/ftp/pub /mnt/nfs nfs bg,soft 0 0 Now, with every Linux since the last millennium one could simply bring down the system into maintenance mode with 'telinit 1', and all worked fine. Now try the same with EL7, do a 'systemctl rescue' or 'systemctl emergency' and see what happens. With lightning speed it does the wrong thing, brings down networked services, brings down the network, and doesn't unmount the NFS filesystems. Then try a 'df' or 'lsof' in rescue mode, it all hangs. Of course I found a solution, mount it with the option 'x-systemd.requires=network-online.target' and it behaves correctly. But really, it's broken, because it's always clear that NFS mounts always only work WITH network! That's just a single small example how things don't work as expected. - migrating from EL6 --> FreeBSD seems easier than migrating from EL6 --> EL7, IMHO. That's really an important point, because those who started using Linux with Linux/systemd will be bound to Linux/systemd with their knowledge, switching to a *BSD or other Unix will be difficult. For me, I don't like to be limited in such ways. In other words, systemd is a new operating system which still lacks a kernel :-) One thing I know for sure: if the *BSD folks were ever going to invent something like systemd, they will do it in a way which hurts less.

That is a community controlled package set .. we need some people from the community to step up and modify / maintain those packages. I have asked again and again, on several fronts (blog, mailing lists, etc), to get volunteers to maintain those packages. I'll ask again now. Does someone from the community want to do the work to maintain those packages? Here are a couple previous attempts: https://blog.centos.org/2014/07/testing-centos-6-to-centos-7-upgrades-via-centos-testing-repo/ https://lists.centos.org/pipermail/centos/2016-May/159326.html We would be very happy to publish those RPMs if we can get them to be maintained by the community, and maintained in a consistent manner.

Re: [CentOS] Can't access Samba shares from Nautilus

OK, I've investigated this a little further, and it looks like I have a partial success. In Nautilus, I pressed Ctrl+L and then typed in the Samba server URL: smb://amandine Now my two shares ("Public" and "Confidentiel") appeared OK in Nautilus. I could mount them and browse them perfectly. So it looks like there's something that prevents my server (amandine) from showing up in Nautilus when I click on "Browse network". Hmmm. Any suggestions ?

[CentOS] Can't access Samba shares from Nautilus
Hi, I'm currently experimenting with Samba on a few sandbox machines. On the server side, I have setup CentOS 7 with a basic Samba setup and two shares, one public, the other password-protected. I have two Windows 7 boxes in my network, and I can access the shares perfectly, log in to the password-protected share, read and write files, so this seems to work OK. On my main Linux workstation (CentOS 7 + custom GNOME) I can't seem to access these shares. When I click on the "Parcourir le réseau" ("Browse network") icon in GNOME, Nautilus opens and shows a "Réseau Windows" ("Windows network") icon. Clicking on this icon, I only get the following error message: "Impossible d'accéder à l'emplacement". Unable to access this place. So I fire up GNOME Terminal and see what this looks like on the command line : [kikinovak@alphamule:~] $ smbclient -L //amandine -N Anonymous login successful Sharename Type Comment - --- Public Disk Partage Public ConfidentielDisk Partage Confidentiel IPC$IPC IPC Service (Serveur de fichiers AMANDINE) Reconnecting with SMB1 for workgroup listing. Anonymous login successful Server Comment ---- WorkgroupMaster ---- WORKGROUPAMANDINE So far, so good. Now I try to connect as a user: [kikinovak@alphamule:~] $ smbclient //amandine/Confidentiel -U kikinovak Enter SAMBA\kikinovak's password: Try "help" to get a list of possible commands. smb: \> dir .
