depends.. eg RedHat keeps weeding out more and more stuff to common
files sourced by all files. Not so sure about the real SysVR4's, but
whatever about the implementation, the idea of runlevels, and init.d
scripts is a good one imo.

you edit the relevant file in /etc/sysconfig.

well ideally there should be tools to deal with that stuff, and failling
that you should be able to fall back to the documentation - which tends to
be more consistent on the commercial unicen compared to RH.
and chkconfig is very handy.

cross pollination is a good thing. :)

i was a big sceptic before i went into the course, (because of SCO
OpenServer 5), but if you're honest you have to admit that SCO UnixWare 7
is very very nice. It really surprised me.

SCO *OpenServer* is inelegant.
SCO *UnixWare 7* is very very decent. Certainly on a par with Tru64 and
IRIX 6 anyway.

it claims to be a leading unix. part of the criteria i have for an os to
meet that claim are that it must strive to be like other unices as much as
that's why i like the lower-profile Tru64 and IRIX 6 unices, (and now
Unixware 7). they're all quite similar. i can take a lot of what i know
and how i work across from one to the other with the minimum of
solaris just has so many little things that are different, that i ended up
not bothering with it.
. Yes, RedHat isn't a SysV, but it styles it's init scripts on theirs.
