I'll look into this once I've got the DLDI-EXT2 bits submitted,
although you need to build in a fakeroot due to mknod being used.

I'll have a look at the upstream uClinux branch, there's e2fsprogs in there,

Well, with an ext2 fs you can have /etc/fstab :-)  dosfsck is ported
now, although it requires extra RAM to function properly.  Really all
that needs doing is to modify rc.common to include something like

# if we have extra RAM, enable 2 extra terminals and gpm
exec 0</proc/meminfo
read line
exec 0</dev/null
set -- $line
if [ $2 -gt 4000 ]
        /usr/bin/agetty -n -l /bin/autologin 38400 tty2 linux &
        /usr/bin/agetty -n -l /bin/autologin 38400 tty3 linux &
        if [ -x /usr/bin/gpm ]
        /usr/bin/gpm -m /dev/mouse0 -t ps2 &
             if [ "$start_fsck" = "YES" ]
             dosfsck /dev/dldi
             dosfsck /dev/dldi1
             echo "Not checking disk"
