So it's looking like we may be just missing a dependency here, so the
bug would be present all the time, but the parallelism is exposing it
more frequently.

Would be worth checking the /etc/init.d/depend files and running
/usr/share/insserv/make-testsuite to see exactly where bootmisc is
being placed in the depdendency graph.  The intention is that this
won't run until after mountall-bootclean.  I /think/ that the
$remote_fs is supposed to ensure this, but this might not be good
enough.  Maybe we need to add mountall_bootclean to $local_fs, or
add X-Start-Before: bootmish.sh to mountall_bootclean.

Could you possible try both of those, rerun insserv, and see if this
prevents the problem from occuring?


Thanks again,
Roger
