[systemd-devel] [PATCH] condition: add option ConditionArchitecture

ExecStartPre= is not about that anyway, because it can be used only in
.service units.

I don't like it too. But can we have other alternatives? Some way ( or
policy ) for extending without systemd patching should be provided,
maybe. I think about using .target as conditions, like
on-battery.target, network at XXX.target, arch at XXX.target, etc with some
other way to push them on. 

Personally I use this approach now (for example, I don't use
ConditionACPower, but battery.target and low-battery.target, which are pushed
by third-party daemon).
