I have cross-filled case 00564055 and 00564056 (different customers) in the 
customer portal at the Red Hat Network.

Comment 5 Bill Nottingham 2011-11-22 15:56:12 UTC
Given we don't ship/support apcupsd in RHEL, I'd be inclined to leave this sort of support for halt.local. I know nut is there, but that predates the RHEL fork.

Comment 6 Robert Scheck 2011-11-22 16:16:11 UTC
This patch is really micro and does definately not hurt any existing customers
of RHEL. See also comment #2, this issue affects paying customers.

Comment 7 Robert Scheck 2011-11-22 16:23:43 UTC
By the way.../sbin/halt.local is NOT suitable for us in this case, because it
is unfortunately executed too early. Remounting remaining filesystems readonly
has to be performed first, otherwise it will cause some other trouble.

Comment 9 Bill Nottingham 2011-11-23 19:02:19 UTC
So, various suggestions:

- Use nut instead. That support is already integrated, and it *should* work for most of the same models, if I'm reading the support page right.

- Use halt.local. You'd need some sleep commands, which would be racy, but it may be hacked to work. (not really recommended)

- Create a custom /etc/init.d/halt script... we don't upgrade that script much, and they'd have to patch it back in place across upgrades, but it could work as a hot fix.

- The code to support nut in /etc/init.d/halt has:

# Shutdown UPS drivers
if [ "$command" = /sbin/halt -a -f /etc/sysconfig/ups ]; then
        . /etc/sysconfig/ups

There's nothing that states that an administrator's /etc/sysconfig/ups couldn't run apcupsd shutdown comamnds when sourced in this way. (Hooray, hacks!)

Comment 10 Robert Scheck 2011-11-23 22:14:50 UTC
Again, this is RHEL and thus IMHO not the place for such hackish suggestions, 
that are either racy or not upgrade-safe. I'm not going to put such stuff on 
productive machines as long as paid RHEL subscriptions are used. I will push
this further on via the customer portal now...

Content of /etc/sysconfig/ups

Hackish suggestion via Red Hat Support Team by abusing /etc/sysconfig/ups
