From e920bfb1e8a5917e7b0f360d1c51d200db3acbfd Mon Sep 17 00:00:00 2001

Subject: [PATCH] fstab: do not mount and fsck from fstab if using systemd
If using systemd in initramfs, we could run into a race condition when
dracut and systemd both are trying to mount and run fsck for the same
filesystem, and mount or fsck could be a failure.
To fix such failure, we should use systemd to mount/fsck from /etc/fstab
only.
v2: check $DRACUT_SYSTEMD suggested by Alexander Tsoy
