I wrote an RPM for RHEL4. The init script of the package does
chkconfig, services, and addgroup/adduser if necessary.

1. Looking for an LDM RHEL-4+ RPM binary or rpm.spec files? If not, I
may be interested in building one for i386 (advice welcome).
2. Does anyone have a ldmd init script for RHEL that can support some of
the advanced RH Linux features listed below (chkconfig, service, PID
files & locks).

I was following the linux-HA Cluster thread & noticed there are some LDM
Docs referencing clusters, but most are geared toward Hi-Performance
Clusters, not Hi-Availability (HA) Clusters. Some configs & principles
(IP Virtual Server) may translate though. For HA clusters, LDM can be
started & stopped via init-scripts in /etc/rc.d/init.d or
/etc/ha.d/haresources as Richard noted.

ldm-binary.rpm specific to RHELvX)
Comparing it to a simple init script like /etc/rc.d/init.d/atd & we may
be able to improve it some & use RHEL service commands, locks & pstools
(pgrep, pkill...) to manage the service like:
# chkconfig --level 345 ldmd on
# service ldmd restart
# service ldmd status
# head /etc/rc.d/init.d/atd | grep chkconfig
# chkconfig: 345 95 5
Note: the chkconfig: line determines runlevels & the priority of kill
and start scripts (man chkconfig)
# service crond status
crond (pid 1117) is running...
# cat /var/run/crond.pid
# ls -l /var/lock/subsys/crond

This may help shutdown & restart the ldmd safely during failover in an
