The configuration option max_open_files defaults to 100,000, but the
salt-master service is only started with a limit of 16,384 open files.
Therefore the higher limit cannot be applied and there will be a log
message:
Current values for max open files soft/hard setting: 16384/16384
The value for the 'max_open_files' setting, 100000, is higher than what
the user running salt is allowed to raise to, 16384. Defaulting to
16384.
This is related to #40173.
Documentation for systemd service files can be automatically viewed
using systemctl help servicename if this field is present. Thus add the
relevant man page, the local and online documentation to the
documentation key.
We actually want salt-master processes in the same control group to be
terminated and this was only introduced to fix the 'minion upgrades
itself' problem, which applies to salt-minion, but not to salt-master.
This change was introduced in d288539 to fix#29295, which discusses the
need to include 'KillMode=process' for the salt-minion on Debian
systems.
Declaring After=syslog.target is unnecessary by now because syslog is
socket-activated and will therefore be started when needed. Thus remove
the obsolete syslog.target from the systemd service files.
Since service files might be used by many distros (arch, rpm-based,
gentoo, mindriva, mageia) I think it would be useful to symlink to
standard ones (and copy and edit them if differences are needed).
