[Voyage-linux] LEDs, APT repository, MySQL in RAM questions

[Sean]

Andreas,

1. You can use a german mirror site for the main debian mirror:

http://ftp.de.debian.org/debian lenny main contrib


The custom repository needs to be there with the main debian mirror. It 
only has additional custom packages related to voyage.

2. I'm not sure about the Missing Packages (adjtimex) on hk.debian.org. 
Maybe try the German mirror?

3. You can put that command line in /etc/rc.local. It will run on every 
boot.
