[gentoo-amd64] local.start conditional on soft-level

[Peter Humphrey]

I'd like my /etc/conf.d/local.start to distinguish between soft run-levels, 
so that "sensors -s" will be run in the default level but not in the no-x 
level I've defined for maintenance.

I recently found something that might do the trick, using (I think) a 
soft-level suffix to the conf.d/ file name, but now I can't find it. Would 
someone please tell me where it is?

Thanks.

The option you are looking for is RC_USE_CONFIG_PROFILE
in /etc/conf.d/rc

sensors -s?  If that's lm_sensors, why aren't you running the lm_sensors
initscript instead of using local.start for it?  It does a bit more
dependency checking and the like.  Is it that you decided you didn't need
all that and just want the simple command, or were you not aware of the
initscript, or ???

Try RC_USE_CONFIG_PROFILE, comment starting on line 53, setting on line
60, of /etc/conf.d/rc (if you've kept the comments and all intact, line
numbering based on the baselayout-1.13.0_alpha12 file).

I'd suggest using the standard lm_sensors initscript, unless you have a
specific reason not to, just because it means system changes that might
otherwise break it are more likely to be fixed by the lm_sensors package
before you even start worrying about it, but then if desired use the
softlevel thing.

Here, however, I just use traditional (aka "hard", I suppose) initlevels,
setting up additional ones as needed.  The only ones normally used by the
system are 0/halt, 1/single-user, 6/reboot (those three nearly universal
Unix), and at least one other "operational" level from those between 2 and
5.  Gentoo normally uses 3/default and 2/nonet, thus leaving levels 4 and
5 free for local use.  In addition, levels 7-9 are available on the
standard Linux sysvinit package, tho those aren't standard across all *ix
like the 0-6 levels are.  Thus, there's plenty of additional levels to
choose and I simply switch between them as necessary using the standard
"init <number>" command, or just add the appropriate number on the command
line if booting directly to something other than my usual default as set
in /etc/inittab.  I don't think I've ever used Gentoo's softlevel stuff,
as I've really had no need to do so.  I'd have to read thru that section
in the handbook again to even know what or how to do with it.  (And yes,
I'm aware I just treated a linguistic inequity as equal.)

That'll be why I can't find it on the Web site then! Thanks Olivier.

[lecture snipped]

Of course I'm using the init script. The lm_sensors documents specify 
running "sensors -s" in addition to that. Sheesh.

What documents?  The generic ones that don't account for the fact that
Gentoo's initscript already takes care of it, you just have to add it to
the appropriate runlevel?

If you read the initscript, you'll see it does in fact include exactly
that initialization command (sensors -s).  Take a look yourself if you
wish.  Unless there's a bug in the script, that should be all you need. 
If there's a bug in the script and it's not working, then file a bug, and
until it's fixed you'll likely need a workaround, but that's not what you
said.

Anyway, lecture or not, the file I pointed you at and its comment
regarding the softlevel conditional initscripts was correct, regardless of
why you want to use it.  It just so happens you shouldn't need to use it
in the way you proposed, tho you /might/ wish to use it with the
lm_sensors initscript. That's what I was saying in that "lecture".  To
quote you, "Sheesh."
