Upgrading Debian GNU/Linux from Sarge to Etch

First, of course, there are the release notes. See http://www.debian.org/releases/stable/

This page is not intended to repeat the release notes, but provides additional notes about goodies that are new in etch but not automatically installed on an upgrade. Nathanael Nerode started a [http://lists.debian.org/debian-devel/2006/08/msg00167.html discussion] about stuff done by the Etch installer which might be of interest to users upgrading from sarge.

  • /proc and /sys are not needed in /etc/fstab anymore (but keeping them is not really harmful.) (["madduck"]: I just installed etch and it still had proc in there; no sys though)
