Install nfsv4-related drivers when users specify nfs dumping via dracut_args
Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=2140721
Currently, if users specify dumping to nfsv4 target via
dracut_args --mount "<NFS-server-ip>:/var/crash /mnt nfs defaults"
it fails with the following errors,
[ 5.159760] mount[446]: mount.nfs: Protocol not supported
[ 5.164502] systemd[1]: mnt.mount: Mount process exited, code=exited, status=32/n/a
[ 5.167616] systemd[1]: mnt.mount: Failed with result 'exit-code'.
[FAILED] Failed to mount /mnt.
This is because nfsv4-releted drivers are not installed to kdump initrd.
mkdumprd calls dracut with "--hostonly-mode strict". If nfsv4-related
drivers aren't loaded before calling dracut, they won't be installed.
When users specify nfs dumping via dracut_args, kexec-tools won't mount
the nfs fs beforehand hence nfsv4-related drivers won't be installed.
Note dracut only installs the nfs driver i.e. nfsv3 driver for "--mount
... nfs". So also install nfsv4-related drivers when users specify nfs
dumping via dracut_args. Since nfs_layout_nfsv41_files depends on nfsv4,
the nfsv4 driver will be installed automatically.
As for the reason why we support nfs dumping via dracut_args instead of
asking user to use the nfs directive, please refer to commit 74c6f464
("Support special mount information via 'dracut_args'").
Fixes: 4eedcae5 ("dracut-module-setup.sh: don't include multipath-hostonly")
