This document describes how to install Debian GNU/Linux 3.1 (sarge) on an IBM Thinkpad T43p. Since I don't have time to write everything in one session, nor am I finished twiddling around with the setup of the notebook, this is work in progress.
When booting the Debian installer via PXE (see the relevant chapter in the Installation Guide for how to setup DHCP/TFTP and where to download the necessary files), the next logical step is to use a local Debian mirror in your network.
Using the entry in the proc-Filesystem of a running process, it's easy to get a sorted list of environment variables for a certain process ID (PID):
tr '\0' '\n' < /proc/<PID>/environ | sort
Since the lines in environ are null-terminated, putting proper newlines in the output with tr is necessary before sorting. (sort can only output lines terminated with \0 using the option -z, but not read them, besides: even -z doesn't quite work as expected in my case)
Oh, this comes in handy:
vimdiff /path/to/file scp://remotehost//path/to/file
Damn, how many features do I actually know of vim? (thanks, Mika for pointing this out, there's even a blog post about it)
