Hm, it works for me: [root@brick:/home/trasz/git/autofs/sys/fs]# mount -t msdosfs -o automounted /dev/md0 /mnt [root@brick:/home/trasz/git/autofs/sys/fs]# mount /dev/ada0p2 on / (ufs, local, journaled soft-updates) devfs on /dev (devfs, local, multilabel) map -hosts on /net (autofs) map -smb on /smb (autofs) map -media on /media (autofs) /dev/md0 on /mnt (msdosfs, local, automounted) Are you sure you've rebuilt mount_msdos(8) binary after the autofs support was committed?
Hmm, you're right. I guess it was a remnant from experimenting with bug 192852.
