Interesting package, but having it installed does not avoid the loss of
most desktop software when uninstalling systemd.

I like only nice words from all people.
In a Debian 9 installed with all defaults, if you change Systemd by
SystemV, you loose most of desktop software.

$ sudo apt install sysvinit-core sysvinit-utils
$ sudo reboot
$ sudo apt remove systemd

(I understand that desktops aren't in the scope of this mailing list)

Can you people obsessed by systemd please drop this advocacy/bullshit?
Debian 9 works fine with sysvinit if this is what the environment 
requires.

Thanks for the well-chosen reference; Steve Litt describes how to
discover that Systemd is replacing GNU. Fortunately, there are other
distributions that will be GNU/Linux for many time.

Hi Narcis,

   Just came across this, which you may find interesting.  Removing systemd
took Devuan two years.

Thanks for all the comments. Note that the wiki guides are for Debian.
Possible needings for concrete 9 version are now explained it this wiki

Yeah, I don't get it either.  I mean, the two main technical strengths of 
Debian are:

1) Support for lots of arches
2) Lots of packaged software

For OpenVZ use we don't really care about either of those... because we only 
care about x86_64 (or maybe some people also still care about i386?).  So far 
as software goes, we'd prefer to have our container host nodes be very minimal 
systems with no unneeded software / services.

So far as using RHEL6 (or free clone), it is a no-brainer because:

1) That's the kernel OpenVZ Legacy is using and the systems they test with
2) It is supported for a long time

It might be true that EL6 has less support time left on it than newer Debian 
releases *BUT* the EL6-based OpenVZ Legacy kernel dies approximately the same 
time that EL6 goes EOL so that isn't much of an issue either.

You can apply these same arguments to OpenVZ 7 but add that Red Hat has 
particular experience in developing and supporting KVM, libvirt, virt-manager, 
etc. since they are the primary developers of those.  Granted, those things are 
important if you don't plan to use KVM / VMs with OpenVZ 7.

Re: [Users] OVZ6 kernel panic on Debian 9

Hi Narcis,

  Looks like our attempts to dissuade you didn't work.    I'm not sure
why you needed to use Debian 9.  Yes, you were able to do it, but now you
have a few potential issues to keep in mind:

Take a look here:.
https://www.reddit.com/r/debian/comments/45frah/remove_systemd_how/

Keep in mind, that was written over a year ago.  Systemd is now much deeper
ingrained.

Second, any system tools or programs that rely on kernel version 4.x will
now break.  Most likely these would be firewall related.  So, any kernel
4.x dependencies might now be broken.  You can check what those are by
listening the dependencies for the 4.x kernel. See here:.
https://unix.stackexchange.com/questions/296196/how-to-upgrade-kernel-with-all-dependencies-in-debian

Specifically: apt-cache show linux-image-amd64

You'd be much, much better off using Centos 6 or OpenVZ 7.  If you insist
on Debian, I suggest you try Devuan, which is Debian 9 based, but has
systemd completely removed.

I suggest that wiki page be edited with these warnings as well.

Good luck!  :)

Alexey, Vasily, you were wrong.
The only barrier in Debian 8 is systemd, and the only additional barrier
in Debian 9 is default Ext4 feature "64bit".

Following the initrd/mount message, I applied a comment from StalkR:
upgrading from Debian 8.
I've installed a clean Debain 8 (with Ext4), upgraded to Debian 9, and
then OpenVZ 6 installs and works (without compiling anything).

Re: [Users] OVZ6 kernel panic on Debian 9

[Alexey Zilber]

It won't work.  Please go through the two earlier responses.   Debian 9
doesn't use initrd, so it will never work.
 Ext4 version is the least of your provlems.

Re: [Users] OVZ6 kernel panic on Debian 9

[Narcis Garcia]

I've debugged initrd steps, and localized an error in this action:
$ mount -r -t ext4  /dev/sda1 /root
EXT4-fs (sda1): error loading journal
mount: Invalid argument

If I try there same command without readonly option:
$ mount -t ext4  /dev/sda1 /root
EXT4-fs (sda1): couldn't mount RDWR because of unsupported optional
features (400)
mount: Invalid argument

I see that Debian 9 installer formats Ext4 with two extra features that
Debian 8 didn't:
64bit metadata_csum

Does anybody know how to "downgrade" Ext4 to remove those 2 features?

Re: [Users] OVZ6 kernel panic on Debian 9

[Vasily Averin]

Dear Narcis,
according to screenshot, you have troubles with initrd image.
Obviously image creation tool on Debian 9 cannot create proper image for old 
kernels.
I doubt it can be fixed.

Thank you,
Vasily Averin

I don't think the OpenVZ Legacy kernel is supposed to work on Debian 8 nor 
Debian 9.

Debian really isn't a good distro for an OpenVZ Legacy host node although 
Debian does have some history with OpenVZ.  For a few releases they had an 
OpenVZ patched kernel in their stock repos... but there were a number of issues 
with it.  Then OpenVZ Project provided kernel was shoehorned to work on a 
release or two of Debian... and I believe it worked fairly well.  One of the 
problems, and maybe not the main problem, is that Debian 8 and 9 use systemd by 
default.  systemd is great but the EL6 kernel (which the OpenVZ Legacy kernel 
is based on) came out in Nov. 2011 and was forked from Fedora 12.  systemd made 
its debut a few releases of Fedora later and became default in Fedora 15.  To 
the best of my knowledge, the OpenVZ Legacy kernel will not work on RHEL/CentOS 
7 for similar reasons.

What kernel is there for newer distros?  Well, the OpenVZ 7 kernel works on 
EL7... but given the expansion of features in OpenVZ 7, they decided it was 
best to make their own distro (basically forked from CentOS 7) and don't really 
support running the OpenVZ Legacy kernel and userland programs on any other 
distro.

Takeaways: If you want to run the OpenVZ Legacy kernel, run it on EL6 or older 
Debians than 8... or give OpenVZ 7 a try.
