 find / -name \*svscan\*
/var/run/svscan.pid
find: /proc/6/fd: Permission denied
/usr/local/bin/svscan
/usr/src/daemontools-0.61/svscan.c
/usr/src/daemontools-0.61/svscan.o
/usr/src/daemontools-0.61/svscan

Svscan is part of the daemontools package as described in "Life". See 2.4
Download Source and 2.7 - Install daemontools. Did you install ucspi-tcp? I
don't know if daemontools is required by qmail, by ucspi-tcp, or by the
plain vanilla instructions in "Life with qmail". Maybe someone can enlighten
us on this point. At any rate I can vouch for a successful installation on
a blue g3 with only one change: in /var/qmail/supervise/qmail-smtpd/run,
the value 2000000 is passed as a parameter to softlimit. In order to get
tcpserver to run properly, I had to increase this value. In changed it to
4000000.

Also, do I need to use the _exact_ same group and user id's for the qmail

> daemons and groups, as the ones pointed in Life With qmail?

Don't know, I just added the groups and user ids as given in "Life". It did
no harm to add them manually.

Attached below is a prototype of three scripts I'll be including on the web
site I'm building

one is a support script for listing the contents of files
two is a support script for ensuring that required entries are added to
configuration files
three is intended to completely configure q-mail

The script as written must run as root. It would be an excellent idea for
anyone running these scripts to read and understand everything the scripts do
before running them. They are derived solely from "Life with qmail" based
verbatim on its contents, but come with no guarantee that they will work and
not do damage on anything but my personal machine. I'm relatively new to
Linux and do not know anywhere near enough to make any statements about the
code's quality.
I welcome constructive criticism of the code, its style and substance.
