I was wondering about submitting a patch to the appropriate ports; if you want to preempt me, feel free :). (The files would presumably need appropriate copyright and license lines added, of course.)

Wow, those scripts are an extremely cool integration of the rcorder framework and the svscan framework. Could these be incorporated into the daemontools and djbdns ports as permanent goodness? I'll give them a try-out myself, pronto. (Might also investigate clockspeed, per Jan's suggestiong, too.)

I'll test it on one of my own machines[1] and I'll incorporate it into the port's options in a couple of days. G'luck, Peter [1] Yes, Andrew, I have the same problem on one machine which is only restarted very rarely, so I just drop a curse and restart ntpd and I couldn't be bothered to actually automate it... sorry for that! -- Peter Pentchev r...@ringlet.netr...@space.bgr...@freebsd.org PGP key:http://people.FreeBSD.org/~roam/roam.key.asc Key fingerprint FDBA FD79 C26F 3C51 C95E DF9E ED18 B68D 1619 4553 The rest of this sentence is written in Thailand, on pgpEivyOr2aKU.pgp Description: PGP signature

I have, in my svscan.sh,
# PROVIDE: svscan
# REQUIRE: SERVERS cleanvar
and I also have a /usr/local/etc/rc.d/dnscache which looks like
#!/bin/sh
# PROVIDE: named
# REQUIRE: svscan
. /etc/rc.subr
. /usr/local/etc/svc.subr
name="dnscache"
rcvar=`set_rcvar`
: ${dnscache_enable:="NO"}
load_rc_config $name
load_svc_subr_config
run_rc_command "$1"
and a /usr/local/etc/svc.subr as attached. It's somewhat more general
than is needed for dnscache, as I also use it to start qmail.
Basically: the PROVIDE: named line is needed to get dnscache up before
ntpd, and the REQUIRE: LOGIN line needs to be changed.
