Subject:      lp support & daemonology
To:           linux-activists@joker.hut.cs.fi

hi all;
       I am working on a print spooler daemon to go along with the lp driver
and have a question about the general init/rc thang. I have installed a test ve
rsion of my spooler ( it's really an exec that has the personality of a daemon
:-) ) in the /etc/rc file but the question is this:
      When a person logs out of bash, the lpd is still busy opening & deleting
files. i.e. it is not safe to turn of the machine & it is possible that it may
seem like nothing is going on. so, is there/will there/should there be some sor
t of rc0 like AT&T uses for shutdown? what do you folks w/uucp do? will this be
in 0.12 & if not it might be a nice project after the lp is mature.
       I have fixed up a bunch of bugs in the lp driver & will post a new versi
on in a day or so. The lpd uses a printcap file & reads the disk as little as
possible to build its queue. The lp should be Posix-compliant and will have a
lot of the features of the BSD lp filter: tab-expand, margins, form size, &
font, all printcap set. What won't be for a while is queue control.
      && thanks for all the info & replies.

When my init is done, what you do is start lp, gettys, and any other
such stuff with runlevel 2. So they get killed when runlevel changes
to 's'. Then write a shutdown script that sets run level to s, then
cleans everything up, kills any remaining demons, unmounts
filesystems, etc. Then syncs a few times, and says "Ready to power
down or reboot" and just sit there.

There is no uucp for linux yet as far as I know. When I get done with
init and login next thing I'll do is try to get Taylor UUCP working.
t is a public domain uucp, pretty comapatible, and with some extra
options..

There are several of us working on it.  I've played with both the Taylor
package and Will Rose's UUCP 1.2  The former needs quite a few library
functions that haven't been implemented yet.  I've made some progress with
the latter but I haven't finished yet, no time :-(
