A page to write useful notes for working in the buildroom.
These are in addition to the useful commands and troubleshooting info in the blue books and as posters on the walls (we hope to get all these on the doc site).
Golden Rules
Check the issue tracker for issues relating to our distro. We also document fixes.

Laptops
To install battery monitoring software:
1.install kpowersave via synaptic or with apt-get
- As root run sysv-rc-conf (the services acpid and acpi-support need to be enabled, use q to quit)

General Hardware Fixes
30-second boot delay on TEACs?
Slow boot times on dells and some other computers? Adds 30 seconds to boot time. Said to occur with x (need to fill this in) manufacturers CDROMS.
To fix:
- Add the following to the file /etc/initramfs-tools/modules
piix ide-disk ide-cd ide-generic
- Execute "update-initramfs -u" as root
- Reboot.

eth0 becomes eth1,eth2,eth3
The reason why it is so is that if hard drive has been in multiple machines, the MAC addresses are remembered in a file called /etc/udev/rules.d/70-persistent-net.rules. To find out the mac address of the ethernet card on your machine type ifconfig on console. The entry HWaddr? is the MAC address. This should be the only entry in that file and should be called eth0. The other file to worry about is /etc/network/interfaces. I would only have an entry for eth0
iface eth0 inet dhcp auto eth0
it's ok to leave entry for ppp0 and wlan0, but i would get rid of entries eth1,eth2,etc.
To test if your changes worked, just type ifup -a or reboot.
