Subject: insserv: uninstallation fails horribly if an init script has been removed

Date: Fri, 11 Apr 2008 01:18:19 +0200

Package: insserv
Severity: important


The following happened to me:
I installed insserv, it reordered the init scripts successfully.
Then I uninstalled a package (in my case it was bootchart).
After that, I also decided to uninstall insserv again.
insserv completely broke down, as it couldn't find the bootchart init
script anymore. Instead it tried to reconfigure all packages that ship
an init script. This completely blew up my system, when it tried to
restart udev.

insserv should be much more careful when it is removed again. If an init
script is no longer present, it should simply skip it and not recreate
the symlinks again.
If a package is installed after insserv was activated (ie insserv has no
backup of the init script priorities), it should only reconfigure this
one package. An even better alternative would be, if update-rc.d would
store/save those priories in the backup for new packages.

[Message part 1 (text/plain, inline)]

Thinking more about it, if update-rc.d also updates the backup file on
package removals and upgrades (not only installs), it would also
gracefully handle this case.

So, I think when insserv is installed and activated, it should create a
snapshot of the current /etc/rc*.d directories.
When packages are removed/installed/upgraded, and they call update-rc.d
in their maintainer scripts, those changes should be recorded in the
backup, so the state is always in sync with the actually installed packages.

When insserv is removed, it should roll back the changes from this
up-to-date backup.

Cheers,
Michael

P.S.: I was tempted to file this bug with a severity higher than
important, as it completely broke my system. A more unexperienced user
would probably have been completely lost.

   [ Petter Reinholdtsen ]
   * Migrate the responsibility for enabling or disabling dependency
     based boot sequencing from the insserv package to the sysv-rc
     package.  Rewrite package description to reflect this (Closes:
     #475478, #511753, #538959).  Keep a dummy update-bootsystem-insserv
     script to avoid having to conflict with sysv-rc version 2.87dsf-2.
     Keep update-rc.d-insserv to make it impossible for the update-rc.d
     diversion to be a dangling link during upgrades.  Make it a copy
     of update-rc.d from the new sysv-rc version to make sure both
     behave the same way.  update-rc.d-insserv should be removed in
     Squeeze+1.  update-bootsystem-insserv could be removed when
     sysv-rc 2.87dsf-2 has been gone from unstable for 3 months.
   * Drop dependencies on sysv-rc, initscripts and sysvinit-utils, and
     leave it for sysv-rc to pull in the packages needed for dependency
     based boot sequencing to work properly.
   * Update README to reflect that dependency based boot sequencing is
     now the default in Debian.  Drop reference to obsolete CONCURRENCY
     setting (Closes: #540447).
   * Add new test case test_override_remove trying to reproduce bug #540866.
     No luck so far.
   * Add new test case test_insserv_virt_loop to reproduce a bug
     reported by Raphael Geissert, where an incorrect insserv.conf will
     make insserv hang forever.  Add new patch 94_v1_12_2.patch from
     upstream to fix it (Closes: #541613).
   * Correct test test_early_all to fail if $all do not work with stop
     sequences.  Add new patch 95_stop_all.patch from upstream to fix
     it (Closes: #542043).
   * Change the definition of $syslog to include rsyslog, sysklogd,
     dsyslog, inetutils-syslogd  and syslog-ng, to include all syslog
     implmenetations in the archive.  Dropped the syslog provide from
     the list, as it should not be used.
   * Update to Standards-Version 3.8.3, no changes required.
   * Add lintian override for the transitient update-bootsystem-insserv
     binary missing a manual page.
   * Add new test test_local_virtual to verify that local virtual
     facilities work properly.
 .
   [ Kel Modderman ]
   * Add new patch 20_install_perms_fixup.patch to install binary and
     conffile with correct permissions.
   * Add new patch 21_tests_suite_new_functions.patch to add a couple
     of new test suite functions to upstream test suite.
   * Make sure update-rc.d compares command line parameters for start/stop
     runlevel configuration with the Default-Start and Default-Stop values in
     LSB info comment of script and warns if there are differences.
