Hi Steve:
Thanks, that's exactly what I needed to know. I'm also putting
together a troubleshooting guide for Linux audio users, and that's the
kind of stuff I need for that work too.
Here's from the chkconfig report:

While some of this report is cryptic to me, I wonder about some things
like the apmd, isdn, pcmcia, portmap, and sendmail entries. Am I correct
to assume I can do without them at any time, i.e., not only during
recording ?
apmd is power management, so turning that off is good, but you can kill that
in you kernel too
isdn - unless you have ISDN hardware it's not doing anything
pcmcia - if it ain't a laptop buh-bye, but if it ain't a laptop you don't have
it.
portmap - only used by NFS, no NFS mounts, you don't need
sendmail - augh, depends on what mode it runs, but if you kill it you won't
get any reports
So, first 3 can be stripped from the kernel, then you don't have to worry even
though they're hardware dependant. Latter 2 can be turned off, but if
sendmail isn't running in daemon mode it's not hurting anything.
BTW - the implementation report dealie is coming along. Should be ready "Real
Soon Now"
Best regards,
