Package: initramfs-tools
Version: 0.92o
Severity: normal

ext3 includes mount option 'data={ordered,writeback,journal}'.
However, it also has a restriction that you cannot change the 'data='
parameter with 'remount'.  Therefore, you have to pass the correct one
at initial mount time, even though the data= parameter does not
directly affect a read-only fs.  If you don't specify, you get
data=ordered.

initramfs-tools should not pick up data= from /etc/fstab, but it does
not.  The workaround is 'rootflags=data=foo' on the kernel command
line.

The consequence is that the root fs cannot be remounted rw:

    EXT3-fs: cannot change data mode on remount
    mount: / not mounted already, or bad option

the recommended way to set is via tunefs:
"tune2fs -o journal_data_ordered" or "tune2fs -o journal_data_writeback"

this specifies the default mountoption in the filesystem superblock.

thus closing as this a much to big special case to start an fstab parser on.
