My original posting was kinda sort of "does this ring a bell?".
Otherwise I would have filed a bug report. It's not that important to me. Was
just curious why it failed. Btw: tried it on my Arch machine, and it works.

What I did was:

1. Booting into rl 1
2. Backup /home (with rsync)
3. mkfs -t nilfs2 /dev/sdaX
4. Restoring /home
5. Fixing fstab with the correct UUID for /home
6. Reboot

My system is fine, and the phenomenon is 100% replicable.
And the behaviour is the same with the latest Fedora kernel from the Fedora
update repo.

Just curious: does cleanerd get invoked when /home is mounted at boot time?
