Description Michal Jaegermann 2007-12-20 22:20:39 UTC

Description of problem:

There could be excellent reasons to mount file systems with
'relatime' options.  After /etc/fstab edits and restarting
the system everything looks just fine.
$ mount | grep relatime
/dev/sda3 on / type ext3 (rw,relatime)
..... (and so on as it was supposed to be).

The catch is that after a kernel update a system does not boot.
The culprit is mkinitrd which is producing in 'init' script
on a boot image a command like that:

mkrootdev -t ext3 -o relatime,ro LABEL=/

and 'mkrootdev' from nash fails on this.  Simply ignoring options
which it does not understand looks like the simplest solution here.

The above can be worked around using an undocumented option
'--rootopts=defaults' to mkinitrd when generating a replacement
boot image.  Unfortunately kernel package scripts are not doing
that.  Another possibility is to hack /sbin/mkinitrd and force
it to always use "defaults" and not bother with /etc/fstab.
Trivial but prone to overwrite on updates.  The best likely
would be to fix nash.

Are there really any good reasons to pass options to mkrootdev?

Version-Release number of selected component (if applicable):
mkinitrd-6.0.19-4.fc8

How reproducible:
always

According to this, relatime is now the default, so you don't really need
relatime support in nash.  Bug #296361 remains open though because it is
probably a good idea to fix nash anyway for safety's sake.
