Thank you. I've written this test case to reproduce the problem. CC
to upstream to let him know about the problem.
test_insserv_virt_loop() {
echo
echo "info: test insserv handle virtual facilities depending on itself."
echo
initdir_purge
list_rclinks
# If $local_fs depend on itself, the error is triggered.
set +C
cat <<'EOF' > $insconf
$local_fs +mountall $local_fs
EOF
set -C
# This will hang and use unlimited amount of memory
insertscript testscript <<'EOF'
### BEGIN INIT INFO
# Provides: testscript
# Required-Start: $local_fs
# Required-Stop:
# Default-Start: 1
# Default-Stop:
### END INIT INFO
EOF
list_rclinks
update_conf
}
We will be careful to not introduce such loops in the
/etc/insserv.conf file included in the insserv package. :)
Of course individual packages can provide extra config in
/etc/insserv.conf.d/, and thus trigger this bug on their own.
Happy hacking,
