I've noticed this behaviour on my Poky/Yocto based systems.
First, I format some device, in this case an MMC card, as ext3
(yes, my kernel supports ext3)
# mkfs.ext3 /dev/mmcblk0p1
Then, when I go to mount it, I get this error:
# mount /dev/mmcblk0p1 /tmp/disk
EXT2-fs (mmcblk0p1): warning: mounting ext3 filesystem as ext2
Any ideas why? How can I get ext3 file system working?
Thanks

This does work although forcing the file system type should not
be necessary, but I'll live with it. This warning/error must have
something to do with the mount program (part of busybox).

Does dmesg complain about the filesystem at all?
FWIW if the datestamps on the filesystem are unusual (e.g, in the
future), this would likely cause problems when mouting them. But
generally I would think that might raise a warning to run fsck, and not
cause an ext3 fs to be degraded to ext2.

Sounds like once again the file mount uses to guess types is out of order.
I think it's part of base-files but I don't have a chance to check right now...

Yes, that's the case.
It's also out of order in upstream oe-core, as compared to the old oe-dev.
Cheers,

Looks like that's it, thanks. I think that list is completely wrong in
its ordering - one should always try to use the *most* capable type first.
The attached patch works fine and solves this problem for me.
