[Pkg-zfsonlinux-devel] Bug#979434: zfsutils-linux: fails to install if zfs module is not loaded

[Andrei POPESCU]

Package: zfsutils-linux
Version: 0.8.6-1
Severity: normal
X-Debbugs-Cc: andreimpopescu at gmail.com

Dear Maintainer,


During install the package tries to start nfs-share.service, which fails 
in case the zfs module is not loaded, for whatever reason[1].


As far as I can tell the start of nfs-share.service is due to

    WantedBy=zfs.target

which is started in postinst.


A quick fix could be to add a condition like for zfs-mount.service, etc.

   ConditionPathIsDirectory=/sys/module/zfs



[1] For some reason when installing the buster-backports package on 
buster the postinst of zfsutils-linux is run before attempting to build 
the zfs module, so this bug is always triggered if installing the 
package by itself (even though dkms-zfs is also installed in the dame 
run, due to the Recommends).


Kind regards,
Andrei
