Hello,
It seems that "Default mount options" from ext3 fs is ignored by
the linux kernel. I have just set "Default mount options" to
"journal_data" on my root fs but kernel still mounts it with
journal_data_ordered:
(part of dmesg)
EXT3-fs: mounted filesystem with ordered data mode.
~~~~~~~~~~~~~~~~~
VFS: Mounted root (ext3 filesystem) readonly.
$ tune2fs -l /dev/md0
tune2fs 1.32 (09-Nov-2002)
Filesystem volume name: /
Last mounted on: <not available>
Filesystem UUID: cfaec15d-a1dc-46fe-af5b-c9f0a087c078
Filesystem magic number: 0xEF53
Filesystem revision #: 1 (dynamic)
Filesystem features: has_journal dir_index filetype needs_recovery sparse_super
Default mount options: journal_data
~~~~~~~~~~~~
Filesystem state: clean
Errors behavior: Continue
Filesystem OS type: Linux
(...)
$ uname -r
2.4.21-pre4
And ofcourse, it is not possible to remount ext3 fs and change
journalling mode.
Best regards,

I am pretty sure you didn't try "append=rootflags=data=journal" did you? :)

Yes. This is true. But if I have to set rootflags= I can't find any reason
for allowing to change "Default mount options". Kernel ignores it, mount
ignores it... Hm....

Well, those option is ignored for your ROOT device. Anything else != rootfs
will work with mount options / fstab.
