Package: lintian
Version: 2.12.0
Severity: normal

Hello,
on last Monday (April, the 22nd) I rebuilt my package (apt-listbugs)
inside a pbuilder-managed sid chroot environment and checked the
result with lintian/2.12.0 (that was the version available from sid
on that day: however, it seems to me that nothing relevant has
changed in version 2.13.0).

I got a new complaint from "lintian -EviIL +pedantic" :
missing-systemd-timer-for-cron-script

Well, nothing to say, that's true: apt-listbugs currently lacks
any systemd timer, but ships a cron.daily script.

Hence, I began doing some research on the proper way to ship a
systemd timer along with an equivalent cron script (while avoiding
conflicts between the two).
I looked for examples in other packages which seem to have already
done this. I think two examples could be man-db and logrotate,
is that correct?

  $ dpkg -L man-db | grep 'cron\|systemd\/system\/[^\/]\+\.timer'
  /etc/cron.daily
  /etc/cron.daily/man-db
  /etc/cron.weekly
  /etc/cron.weekly/man-db
  /lib/systemd/system/man-db.timer
  $ dpkg -L logrotate | grep 'cron\|systemd\/system\/[^\/]\+\.timer'
  /etc/cron.daily
  /etc/cron.daily/logrotate
  /lib/systemd/system/logrotate.timer

I even looked inside these files, and it seems to me that the systemd
timer is really equivalent to the cron script (in both cases).

But, to my great surprise, I see that lintian [complains] [about] those
two packages, as well!

[complains]: <https://lintian.debian.org/full/cjwatson@...#man-db_2.8.5-2>
[about]: <https://lintian.debian.org/full/cgzones@...#logrotate_3.14.0-4>

Are these false positives?

I took a look at the [code] that implements the check.

[code]: <https://salsa.debian.org/lintian/lintian/blob/master/checks/systemd.pm>

I have a question: is the following line

    return if any { m,^/lib/systemd/system/\.timer$, } $info->sorted_index;

missing something in the regexp?
Should it be

    return if any { m,^/lib/systemd/system/[^\/]+\.timer$, } $info->sorted_index;

or anyway something able to catch some characters between
"system/" and ".timer" ?

I am not sure this is the cause of the false positives, though.

Of course, I can well be completely off-track, so please bear with me!

Please clarify.
Thanks for your time!
