Shouldn't it be doing the mount 'silently' when mount(8) is guessing the filesystem type? I'm seeing this too (2.2.19 + ext3 0.0.6b):
lilith:tmp$ cat /etc/filesystems ext3 vfat lilith:tmp$ grep floppy /etc/fstab /dev/fd0 /floppy auto noauto,nodev,nosuid,user 0 0 lilith:tmp$ # with a VFAT filesystem on /dev/fd0: lilith:tmp$ mount /floppy VFS: Can't find an ext3 filesystem on dev fd(2,0).
Looking at the kernel source, read_super (and hence ext3_read_super) are only called with silent=1 when mounting the root filesystem. I believe mount(8) checks for magic numbers at the start of the filesystem, and so avoids attempting a mount for ext2 or various others.
As the kernel (2.2 or 2.4) doesn't seem to provide a way for userspace to request a silent mount, I don't know whose (if anyone's) bug this is.
