- Add 0001-logind-keep-backward-compatibility-with-UserTasksMax.patch
  We have to keep support for UserTasksMax= for a while before
  dropping it. This patch is supposed to do that and also to make
  users aware of this change. It also hints how to configure that
  differently.

Subject: [PATCH] logind: keep backward compatibility with UserTasksMax= in
logind.conf
Since commit 284149392755f086d0a71, UserTasksMax= support has been simply
dropped.
A generator is used to automatically create an appropriate dropin that has the
same effect. However since the snippet is generated in /run, sysadmin is
encouraged to copy it in /etc to make it persistent.
The main advantages to use a generator are:
- sysadmin is aware of this backward incompatible change
- he will be the one who will fix logind.conf manually (to remove the use of
UserTasksMax=)
- he will decide how to name the snippet and possibly merge it with an
existing one
Expect this generator to be dropped in the future.
