#priority(arg = nil) ⇒ Object

Priority arguments can have two forms:

  • a simple number, in which the default start runlevels get that as the start value and stop runlevels get 100 - value.

  • a hash like { 2 => [:start, 20], 3 => [:stop, 55] }, where the service will be marked as started with priority 20 in runlevel 2, stopped in 3 with priority 55 and no symlinks or similar for other runlevels
