system was not booting up properly with a nilfs2 root filesystem. initially passno for / was set to 1, it was complaining about not finding fsck.nilfs2. when I switched passno to 0, the root filesystem was not being remounted R/W and a lot of things were going horribly wrong. symlinking /sbin/fsck.nilfs2 to /bin/true and reverting passno back to 1 didn't fix the issue yet, but changing checkroot to remount / R/W upon successful fsck did the trick. Not sure if this is the cleanest solution, or a horrible hack, but it works for me and I'll stick to it for the time being. Reproducible: Always Steps to Reproduce: 1. create a nilfs2 filesystem 2. edit your /etc/fstab to use the nilfs2 filesystem as /, with either passno 1 or 0 3. reboot... and see what happens... thanks!

This bug fucusses on the aspect that: - when fstab states "0 0" , fsck should not be called at all, and mount should be tried - when fsck failes, or is not found, a clear explicit error message should be printed - the nilfs-utils package should provide a fake fsck to make checkfs/checkroot/checkall (depending on baselayout version) happy.
declaring anything other than 0 in your fstab means your fstab is wrong. i'd punt this to nilfs upstream to see if they want to do anything about it. but there is no requirement whatsoever that baselayout/openrc needs/wants a fake nilfs fsck program.
The problem lies in the following lines of the checkroot script: # Should we mount root rw ? the touch check is to see if the / is # already mounted rw in which case there's nothing for us to do if mount -vf -o remount / 2> /dev/null | \ awk '{ if ($6 ~ /rw/) exit 0; else exit 1; }' && \ ! touch -c / >& /dev/null then to be precise in the 'mount -vf -o remount /' part. Normaly 'mount -vf -o remount' should return something like: /dev/sda3 on / type ext3 (rw,noatime) but when using mount.nilfs2 the output (stdout) not only depends on circumstances, but also includes some additional lines. When issued on a 'rw' mounted system it returns something like: mount.nilfs2: kill cleanerd (pid=3728) on /dev/sda2 mount.nilfs2: cleanerd (pid=3728) stopped mount.nilfs2: started nilfs_cleanerd /dev/sda2 on / type nilfs2 (rw,noatime,gcpid=3734) (and it is all in stdout - stderr has been passed to /dev/null) As for 'ro' mounted systems the output is a single line: nilfs_cleanerd not started My solution is to change the script like this: # Should we mount root rw ? the touch check is to see if the / is # already mounted rw in which case there's nothing for us to do # if mount -vf -o remount / 2> /dev/null | \ # awk '{ if ($6 ~ /rw/) exit 0; else exit 1; }' && \ if \ ! touch -c / >& /dev/null then I'm not sure if I could call it a good solution, but it seems like one, especially that '! touch -c / >& /dev/null' should be enough to check if the filesystem is mounted readonly.
