Subject: [PATCH 2/2] mountlist: recognize more file system types as remote
Sync "remote" file systems from stat.c in coreutils.
Note we only consider file systems that do not use host:resource
mount source. I.e. those that don't generally use a colon when
mounting, as that case is already considered. Searching for
"<fstype> /etc/fstab" was informative for identifying these.
The full list of "remote" file systems in coreutils is currently:
acfs afs ceph cifs coda fhgfs fuseblk fusectl
gfs gfs2 gpfs ibrix k-afs lustre novell nfs nfsd
ocfs2 panfs prl_fs smb smb2 snfs vboxsf vmhgfs vxfs
Note also we do not include virtual machine file systems,
as even though they're remote to the current kernel,
they are generally not distributed to separate hosts.
* lib/mountlist.c (ME_REMOTE): Sync previously unconsidered
"remote" file systems from stat.c in coreutils.
