unsupported centos release 'CentOS Stream release 8' (with fix)

[adreyer]

The LXC hook scripts do not recognize the numbering scheme for Stream releases. There is a simple fix:

root@pve:~# pveversion
pve-manager/6.2-12/b287dd27 (running kernel: 5.4.65-1-pve)

root@pve:~# diff -u /usr/share/perl5/PVE/LXC/Setup/CentOS.pm{.orig,}

Thanks for digging into the issue and coming up with a fix.

Could i ask you to send it to our development mailing list with a Signed-off-by tag - see our Developer Documentation:
https://pve.proxmox.com/wiki/Developer_Documentation#Working_on_the_code

Also - how did you get to that situation (so that we can reproduce it here locally)

Thanks again!

History:
I had some LXC containers build with CentOS8, added the Stream repositories and updated all packages. Rebooted the container from within and everything was running fine for quite some time.
I have updated proxmox/PVE a few times without rebooting the host or the containers. Today I had a power outage and when trying to start up all containers, those running CentOS Stream (release 8) failed to start. Digging into it I found that the Stream release was not detected and a look at the code showed that only release numbers with one or two dots are recognized as valid. However, Stream releases only have the major version number.

Patch sent to the devel list.

The patch was held for moderation (if possible please subscribe to the pve-devel mailing-list: https://lists.proxmox.com/cgi-bin/mailman/listinfo/pve-devel) - I just released it and will try to give it a spin
