Description fbusse 2005-02-19 02:02:15 UTC

Hi
I've got an interesting problem.
/etc/fstab contains:

/dev/sda1 /mnt/usb vfat noauto,user 0 0

/etc/filesystems (symlink to /proc/filesystems) contains (removed the lines with a starting nodev):

ext3
ext2
iso9660
udf
vfat

According to the manpage, mount will check /etc/filesystems if the superblock turns up nothing useful (which IMO is the case for vfat at least the manpage suggest so in the paragraph about floppy). So mount should try to mount /mnt/usb as vfat, but it doesn't:
$ mount /mnt/usb
mount: unknown filesystem type 'msdos'

Why does mount try to mount it as msdos? Doing a mount -t vfat /dev/sda1 /mnt/usb works fine, so there's no problem with mounting itself, just with the detection.
Is there something wrong?

/etc/filesystems  should not be a symlink to /proc/filesystems.
get it from base-layout instead.

$ cat /var/db/pkg/sys-apps/baselayout-1.9.4-r6/CONTENTS |grep filesystems
sym /etc/filesystems -> ../proc/filesystems 1098868535
