[pve-devel] [PATCH 2/2] integrate meta packages and change prefix

Fabian Grünbichler f.gruenbichler at proxmox.com
Tue Jul 18 11:11:01 CEST 2023 

long overdue, and avoids the issue of the meta packages version going down
after being folded in from the pve-kernel-meta repository.

the ABI needs to be bumped for every published kernel package now that modules
are signed, else the booted kernel image containing the public part of the
ephemeral signing key, and the on-disk (potentially upgraded in-place) signed
module files can disagree, and module loading would fail.

not changed (yet): git repository name, pve-firmware

Signed-off-by: Fabian Grünbichler <f.gruenbichler at proxmox.com>

Notes:
    we could also unify KREL and PKGREL now, since the two always need to be bumped together?
    
    not changed yet: git repo, pve-firmware package - those can be done as follow-ups though.
    
    we could possibly add a Breaks on all the outdated meta packages here, but I
    think just bumping coming from the other direction should be enough:
    
    proxmox-ve/proxmox-backup-meta/proxmox-mailgateway -> proxmox-kernel-6.2 -> updated proxmox-kernel-6.2.16-...
                                                       -> updated proxmox-kernel-helper
    pve-headers -> proxmox-kernel-6.2 -> updated proxmox-headers-6.2.16-..
    
    note that PMG calls the top-level headers meta package pve-headers as well, and
    PBS doesn't even have it in the first place. we could rename (and
    Breaks+Replaces+Provides) for PMG, and add it to PBS as well, if desired.
    
    changelog diff included because of the source package rename (easy to miss
    otherwise) - can of course be extended/.. if more changes are folded in before
    actually building and releasing!
