[PATCH v2] spec: Fix 'libvirt-daemon-driver-storage-zfs' on Fedora 43 and newer

24 Nov 2025

From: Peter Krempa <pkrempa@redhat.com>

On Fedora 43 and newer the 'fuse-zfs' package was removed. Commit
bd30147e740 added an 'Obsoletes' directive so that the storage driver
core package will update properly but hardcoded the obsoleted version
as 11.4 (when the change was comitted) similarly to the old sheepdog/rbd
packages and disabled the build.

Now it is still possible to obtain ZFS support from other means and it
may be useful for users to have libvirt's ZFS backend. This patch thus:

 - re-enables build of 'libvirt-daemon-driver-storage-zfs' on Fedora
 - removes 'libvirt-daemon-driver-storage-zfs' as 'Requires dependency
   from 'daemon-driver-storage' meta-package on Fedora 43 and newer

With this the package still is built and installable but will require
users to get their ZFS support installed somehow.

Fixes: bd30147e740d49fdb5844160e480ca34611f75e5

I originally thought that the 'Requires' dependancy requiring
/sbin/zpool and /sbin/zfs would need to be dropped but even without
'zfs-fuse' on F43 it builds fine.
