(Why did you think that an initrd would be a special case if you didn't
know what one was?)

Hmm, surely they wouldn't be so silly as to have ext3 support built as a
module...?  Nope, you're right, they have.  OTOH it appears to be
included in the default set of initrd modules, ext3 root fs or no.

Also it seems as though you don't even need to tune2fs -j the root
partition if you're using Debian's initrd scripts:

(cameron at erdos ~) cat /usr/share/initrd-tools/scripts/e2fsprogs.mkinitrd 
#!/bin/sh
ext3root=`grep -v '^ *#' /etc/fstab | awk '{ if (($2 == "/") && ($3 == "ext3")) {print $1;}}'`
if test -n "$ext3root" ; then
    /sbin/tune2fs -O has_journal $ext3root > /dev/null
fi

(I'm not even going to ask how one goes about rebooting Craig Ringer.)
