I am looking for some feedback from people running Linux on HP Proliant hardware, specifically the ML110 G3. I have heard from Wouter V.( http://grep.be ) that he has installed Debian on ML100 servers using the kernel provided at http://kmuto.jp/debian/d-i/ . This was required for full SATA support.
The Debian Wiki notes that the ML110G4 works on the D-I from 2006-11-21.(Even mentions that the RAID works with the cciss drivers.
Has anybody run the HP Lights-Out Drivers and Agents (hprsm) on the ML100 hardware with a LO100c card?? Any information would be greatly appreciated.

On my IBM T42 work laptop running Ubuntu "Drake"(FGLRX drivers from the xorg-driver-fglrx package) I found that the GPU temperature was at 120F when idle. First, I did not like that the fan was running all the time(now that it is summer) just to cool an idle chip. Second, I did not like this additional drain on the batteries.
Using info gleaned from here[thinkwiki.org] I did the following:
Created /etc/acpi/ac.d/fglrx-powersave.sh:
ATICONFIG=/usr/bin/aticonfig
if [ -x $ATICONFIG ] ; then
getXconsole
su $user -c "($ATICONFIG --set-powerstate=2)"
fi
And /etc/acpi/battery.d/fglrx-powersave.sh
ATICONFIG=/usr/bin/aticonfig
if [ -x $ATICONFIG ] ; then
getXconsole
su $user -c "($ATICONFIG --set-powerstate=1)"
fi
It helps somewhat. The fan still runs continuously but now the GPU only runs at 115F when idle. There is always Rovclock[thinkwiki.org]. Maybe I'll try that later.(it seems to me that a "powernowd" for the GPU is what we need. How would one gauge the load on the GPU though?)
Assume that a user wants to install an application, lets call it 'GFoo', and s/he runs a point and click installer and it says one needs to also install the dependency 'tBar' - the hard to use command-line application that GFoo is a GUI for. The user just says 'Ok' and has the application installed.
Now when the user no longer wants 'GFoo' and removes it, s/he will most likely end up with tBar just laying around taking up disk space.
So with the perspective of packaging applications for the ordinary desktop user - where we don't want to bother them with concepts of dependencies and orhpans - can the packager also prompt the user if s/he wants to remove 'tBar' when uninstalling GFoo? Is there a Debian Policy legal way of doing this?
So I found myself with the results a bad choice: "Hey, THAT bleeding edge package update will suit my needs perfectly!" Well it did not. So I downgraded:
$ sudo $EDITOR /etc/apt/sources.list [ disable the repository that I got the package from] $ sudo apt-get update $ sudo dpkg -P --force-depends the-package [insert various warnings here] $sudo apt-get install the-package
Carefull here. Note the '-P' switch meaning 'PURGE config'. Backup your valued configs first! I needed to purge the configs because I knew that they may not have been compatible between versions.
Ok, now what about the numerous dependencies that I did not pay any attention to during the upgrade? I want to make sure they are back to their original versions also. What I really wanted was a way to list all installed packages that have version numbers greater that what is in the APT cache(in the repository). Enter 'apt-show-versions'.
$ sudo apt-get install apt-show-versions $ apt-show-versions | grep ' newer ' lib-the-package 3.1415-9 newer than version in archive ...
Excellent. Now just remove and reinstall.

A quick little script to automatically enable Firestarter[1] when Network Manager[2] enables an interface. This is for Ubuntu/Breezy or bleeding edge Debian. Put it in /etc/NetworkManager/dispatcher.d
#!/bin/sh
source /etc/firestarter/configuration 2>&1
# Check to see if the interface that changed is the one currently
# protected by firestarter. If not, quit.
[ "$1" != "$IF" ] && exit
# Check the current status of Firestarter
[ -e /var/lock/subsys/firestarter -o -e /var/lock/firestarter ]
fs_status=$?
case "$2" in
up)
[ "$fs_status" -gt 0 ] && /etc/init.d/firestarter start
;;
down)
## Uncomment the following line to allow this script to
## turn off the firewall when the interface goes down.
#[ "$fs_status" -eq 0 ] && /etc/init.d/firestarter stop
;;
esac
By default it does not disable the firewall when the interface goes down because I prefer to do that myself. [1] http://packages.debian.org/stable/source/firestarter, http://fs-security.com/

INITRD_OK=yes make-kpkg \
--initrd \
--revision=1 \
kernel_image
yet no initrd image is created in the package. There is no indication that it is even trying. Of course I can create one manually, but I would prefer to have it in the same package for our internal package repository.
