ext3/ext2 compatibility; time for ext3 in mainline kernel?

ext3/ext2 compatibility; time for ext3 in mainline kernel?

[Dan Kegel]

I installed Red Hat 7.2beta, and chose its nifty ext3 option when
setting up my partitions.  But now when I boot into vanilla 2.4.9,
some files are mysteriously missing, notably /usr/bin/id and
/usr/lib/libreadline.so.3, judging from the error messages that spew
when I try to do anything.

I guess either a) there's a bug, or b) ext3 isn't so compatible with ext2
that you can just boot into an ext2-only kernel and expect things to work.

If b) is true, I'd really really like vanilla 2.4.11 or so to support ext3.
Isn't it about time?

First beta or second?

The first was full of weird bugs like that -

The second beta has been running solidly here.

This should definitely work. If the journal has not been played back then
you may not be able to mount the fs as ext2. The case where it mounts as
ext2 but the journal is not played back or there are incompatibilities
showing is a bug.

Er, nevermind.  I needed to do
   mount -t ext2 -L /usr /usr
