Loops involving virtual facilities ignored?

Hi, Werner. I just got a report about a init.d script dependency loop
in Debian which apparenly is only a problem some times with insserv.
Check out <URL:http://bugs.debian.org/554905> for the details.
I've tried to reproduce the problem with this testsuite fragment, with
a loop between mdadm -> mountall -> hibernate-cleanup -> mdadm. Why
do insserv not fail to accept this configuration?
test_undetected_loop() {
set +C
cat <<'EOF' > $insconf
$local_fs mountall
EOF
set -C
insertscript hibernate <<EOF
### BEGIN INIT INFO
# Provides: hibernate-cleanup
# Default-Start: S
# Default-Stop:
# Required-Start:
# Required-Stop:
# Should-Start: udev devfsd raid2 mdadm lvm evms cryptdisks
# X-Start-Before: mountall
### END INIT INFO
EOF
insertscript mountall.sh <<EOF
### BEGIN INIT INFO
# Provides: mountall
# Required-Start:
# Required-Stop:
# Default-Start: S
# Default-Stop:
# Short-Description: Mount all filesystems.
### END INIT INFO
EOF
insertscript mdadm <<EOF
### BEGIN INIT INFO
# Provides: mdadm
# Required-Start: $local_fs
# Required-Stop: $local_fs
# Default-Start: S 2 3 4 5
# Default-Stop: 0 1 6
### END INIT INFO
EOF
echo $insconf
cat $insconf
list_rclinks
}
Happy hacking,
