[gentoo-user] Non-opnerc init scripts

Hi,

I use oss4 directly from upstream now. It comes with an legacy init
script that works well with `/etc/init.d/oss start` (however, it has no
status).

I added it to the "default" runlevel but unfortunately, openrc does not
even try to start it.

Could anyone give me a hint what I could have oevrlooked?

Regards
   Klaus

openrc scripts have their own "API".  Converting a straight sysvinit
script into an openrc one takes some work.  Look at some existing
openrc script to see the kind of work that is needed.

A quick workaround is to just put your oss script under /etc/local.d
with a name ending in ".start".

Unless the upstream script does quite a bit you're usually better off
starting with a generic OpenRC init.d script and just tweaking it vs trying
to convert a non-openrc script into an openrc one.

Another option is to just create an openrc script wrapper that just calls
the upstream one, which is installed elsewhere.

Ideally though you want to get pid files and such to show up in the right
place.  However, if this is for oss I'm not sure you're even launching any
daemons vs just setting mixer levels and such.  If you aren't actually
leaving any processes running calling the upstream script from a wrapper
should be pretty harmless.  I haven't used openrc since it got cgroup
support but I suspect it is better about cleaning up orphans these days as
well.
