Proposed MBF: rcS init scripts with no equivalent systemd service file

[Felipe Sateler]

Hi all,

I'd like to file bugs (severity: important) on packages that ship an
init script that installs into runlevel S, but do not provide a
systemd service for it. I plan to use the init-rcs-service [usertag]
to record all filed bugs.

=== BEGIN TEMPLATE ===

Hi,

Your package has an initscript that is enabled in runlevel S, but it
does not provide a corresponding systemd service unit.

Systemd generates units for all sysv init scripts that do not have a
corresponding systemd unit. By default, it sets
DefaultDependencies=yes, which means they get ordered after early
boot.

The problem is that to preserve the runlevel S semantics, systemd in
debian is currently[1] ordering all S services Before=sysinit.target.
This target is particularly early in the boot sequence, which means
that it is most of the time too strict. In turn, this means it is
fairly easy to end up with dependency cycles. For an example, see bug
[763315]. Do note that the cycle still exists with sysvinit, it is
just that systemd complains more loudly.

The solution is straightforward: create a systemd unit for the given
service with the appropriate dependencies, which most of the time will
be less strict than Before=sysinit.target. In other cases, the script
is simply not applicable in systemd (eg, if the units are named
differently), in which case the package should ship a symlink to
/dev/null as /lib/systemd/system/<initscript>.service. If you have any
other doubts, feel free to ask in

=== END TEMPLATE ===

I have used the new lintian systemd-no-service-for-init-rcS-script
[tag] to compile a list of packages that are affected. Some
maintainers are already aware of the problem. If you are working on
this and prefer not to have a bug filed, or there is already one
filed, please let me know. AFAIK setserial is the only one that has a
bug already filed [786976].

, but there are some false positives in this list.
