It's another question.
the main goal of this patch is that supports conditional execution
If some services are executed with given condition, it should check
some conditions and execute different flow.
if [ condition is 1 ]; then
    launch A service
else if [ condition is 2 ]; then
    launch B service
    launch C service

current systemd scheme we have to prepare three service file. so can
we make it only one service with some unit extension? IOW multipul
unit support?



ConditionBlahBlah=!1 && !2 or empty line

Thank you,
Kyungmin Park
