Mounting as ext2 is a useful technique for determining whether the fs is

What's the preferred way to try to convert a root filesystem to a bigger
journal? Forcing "rootfstype=ext2" at boot and boot into single-user, and
then the appropriate magic tune2fs? Or what?

Gee, it's been ages. umm,

- umount the fs
- tune2fs -O ^has_journal /dev/whatever
- fsck -fy (to clean up the now-orphaned journal inode)
- tune2fs -j -J size=nblocks (normally 4k blocks)
- mount the fs

I think this is overkill, but should of course be safe.

While you're doing this anyway, you might want to make sure you enable -O +dir_index and run fsck -D.
