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. -- Craig Rodrigues rodrigc@crodrigues.org
