OK, i agree, that's not nice.
There's another way, but i had to check the code to be sure it was
implemented...
The other thing we can do is to check for success at the first attempt
to register something, that way we avoid the problem of trying to
register something more than once, but we still need to set $SERVICE.
We can provide a function for that (we will put this kind of functions
in the wrappers), that way it will look better:
ireg()
{
export SERVICE="${2}"
iregister "${1}" || exit 1
}
So the scripts will look like:
setup()
{
ireg service service/some_service
iset need = system/bootmisc
iexec start
idone
}
btw, the $NAME variable isn't set correctly, imo:
$SERVICE = system/udev/udevd -> NAME = udevd (OK)
$SERVICE = system/udev -> $NAME = udev (it should be '')
$SERVICE = system/udev/some/other -> $NAME = other
(it should be 'some/other')
I will try to find some efficient fix.
