That's a bit frustrating, I thought we had this nailed now.

Would it be possible to debug this in a bit more detail on
your system?  /lib/init/bootclean.sh's clean function must
be failing all these checks:

        # Does not exist
        [ -d "$dir" ] || return 1
        # tmpfs does not require cleaning
        [ -f "$dir/.tmpfs" ] && return 0
        # Can clean?
        checkflagfile "$dir" || return 0
        # Already cleaned
        [ -f "${dir}/.clean" ] && return 0
        # Can't clean yet?
        which find >/dev/null 2>&1 || return 1

Could you possibly put some print statements in there and find
out if all these pass?  If so, is the ".tmpfs" file missing?
Or the ".clean" flag file?  If that's the case, we really need
to know why they aren't present, since they should have been
created before this point.

If the init scripts are being run in the wrong order, these
could potentially be run after the files were deleted.


Thanks,
Roger
