Re: Any good Debian books highly recommended
Regarding the following, written by "jeremy ardley" on 2024-08-26 at 09:58 Uhr GMT: It's almost 20 years old now but it's still pretty relevant since Debian hasn't changed that much. 20 years old means it's missing all the systemd stuff. That's quite important. True. However, systemd is also not Debian-specific, and just like I never covered specifics of the Linux kernel or GNU utilities, I am no sure how much of systemd would actually have its place in this book. That said, there's a lot of coverage of `init.d` and related Debian hacks, such as `update-rc.d`, which are now no longer really relevant. So yeah, the book is ancient, no irrelevant, but I've also moved on with life and won't have the time to write an updated version. If anyone cared enough to do so, I'd happily put you in touch with Open Source Press (the original publisher) and/or NoStarch.

If you want to use either, you need to ensure that you're properly logged in as the user, or configure your system to set up the dbus session accordingly. An easy way to do this is to use `ssh` with X-forwarding: ``` ssh -X u@localhost ``` and then try it again.

xdg-open pain, how to use run-mailcap

I don't want .desktop files and I don't want to have to create underdocumented ini-style configuration just to get my computer to do again what it always did: use run-mailcap, which I can configure with simple text files and which continues to do its job just fine and never needed replacement anyway.

Enforcing g+rwX permissions on shared files
Hey folks, turning to the larger audience in search for new ideas… since POSIX is based on discretionary access control (meaning that the application/user have the final say), and after Samba 4 dropped the "force directory security mode" & Co. settings, we are finding it really hard to provide a good filesharing means between users of all platforms (shell, some desktop-environments, Windows, MacOSX) without constantly running into problems relating to the group permissions. So far, I have not found any way to ensure that everyone using a CIFS share (or NFS, or Appletalk, or SSHFS, or Git, or whatever) is forced to leave the file repository in a state where all files and directories are owned by a shared group and have the g+rwX bits set. g+s on the directory (as well as the Samba "force directory mode" setting) do not affect existing files moved into the tree, which is what happens most of the time actually. ACLs also don't work, since they are ultimately governed by the group bits, which get interpreted as mask. Short of the sledgehammer approaches of using either a cronjob to brute-force permissions at regular intervals, or an incronjob to pave over any changes right when they happen, I am at a loss. And I'd like to avoid both those hacks because they are just ugly and spell trouble sooner or later, I am sure. How do solve this?

I don't think this is the case. The CTTE's decision was IMHO based largely on the trust that we, as Debian, could help systemd reach our standards. There were/are very strong arguments for some of the technology and innovations around systemd. The main counter-arguments were IIRC the monolithic design, and the unapproachable upstream team. The CTTE ruled that those could be overcome and then the benefits would win. > From my own perspective, I don't know about "Debian standards" in > any detailed and specific way, but "shaping systemd" so that it > meets *my* standards in that regard would involve changes which > have been explicitly pre-rejected by upstream - and would quite > possibly require either major re-architecting or even redesign, > and maybe even dropping some of the features and/or functionality > which it currently provides. I hear your cries, and we could howl together if you want. And I really wish systemd would exist in Debian experimental and nowhere else for now. But the reality is that progress is driven during the Debian release cycle. And while this might mean that jessie will hurt a lot of people, ultimately, it'll advance us.

Before doing so, I agree it would be necessary to carefully assess the existing forks first though. However, I would be surprised if the possibility of a fork wasn't part of the consideration of the CTTE when they made this (awefully difficult) decision. We are Free Software (or Open-Source, whatever), we try to avoid duplicate work through the reuse of code. A lot of interesting work is being done based on the systemd innovations. Believe me, I *don't* like systemd and what it forces me to do, but it'd be silly to forego all this derivative work by deciding to split from the herd. Instead, let's make our way to the front and lead the herd. This is what Debian has done in the past, and what we should do again in the future. We haven't been able/motivated to do this with all the *Kit software, while it was mostly optional. Systemd currently isn't optional. I hate that.

I'll take a shot into the dark: does it work if you add rootdelay=30 to the linux kernel boot line? E.g. kernel /boot/vmlinuz ro root=/dev/md0 rootdelay=30 This will incur a 30 second delay during boot.
