drbd-reactor v1.5.0-rc.1

[Roland Kammerer]

Dear DRBD users,

this is the first RC of the upcoming drbd-reactor version 1.5.0. There
are smaller fixes and improvements all over the place, the important
changes happened in startup of the daemon and the promoter plugin:

We have customers that have hundreds of promoter resources managed by
drbd-reactor. So far every instance on startup wrote their systemd
target units and then called `systemctl daemon-reload`. That takes some
time and in sum systemd might kill the drbd-reactor service because it
did not start in time. We now call daemon-reload only once, and we
improved sd_notify(3) communication between reactor and systemd. Startup
with lots of plugins should now be faster and timeouts should no longer
be a problem.

Please test, if we don't find any bugs I will do the final release in
about a week from now.

Regards, rck
