What about cases where there may be several matching file systems?
For instance, a clean ext3 file system is also a valid ext2 file
system (and vice versa).
Currently, FreeBSD can only mount ext2 with mount -t ext2fs.
A better example would probably be udf and cd9660 filesystems.
Right now the logic is to iterate over the list of known local
filesystems (always starting with "ufs"), skipping over "synthetic"
and "network" filesystems,
i.e. similar to the list produced by lsvfs:
Filesystem Refs Flags
-------------------------------- ----- ---------------
ufs 8
reiserfs 0 read-only
nfs4 0 network
ext2fs 0
ntfs 0
cd9660 0 read-only
procfs 1 synthetic
msdosfs 0
xfs 0
devfs 1 synthetic
nfs 0 network
The first matching filesystem wins....not perfect, but
maybe good enough for a lot of cases.
mount -t always works if you want to specify the fstype.
