[aur-general] Systemd service files

[Limao Luo]

In general, should .install files enable systemd service files on 
startup by default (even if some custom config may or may not be 
required)? Are there any other special considerations when deciding? [1] 
provided some info about systemd scripts, but I couldn't find anything 
as it relates to PKGBUILDs.
