I haven't read this one yet, but I've been noticing a big improvement on the quality of documentation around Squeeze. Maybe I'm just being subjective here, but I don't recall Lenny's being as well presented.
10 minutes browsing through the handbook and I already found great info that I did not know:
The Debian package format is designed so that its content may be extracted on any Unix system that has the classic commands ar, tar, and gzip. This seemingly trivial property is important for portability and disaster recovery.
I've been waiting for Linux distributions to pick up the idea behind FreeBSD's handbook (http://freebsd.org/handbook) which is an absolutely fantastic resource that has helped me even as a veteran FreeBSD user make sure I had all my ducks in a row before making modifications to my system.
After just superficially skimming through the FreeBSD handbook, it seems similar to Red Hat's Deployment Guide . Red Hat has lots of other useful documentation on topics like storage and virtualization administration .
"This Debian Reference (v2) (2012-03-25 12:47:43 UTC) is intended to provide a broad overview of the Debian system as a post-installation user's guide. It covers many aspects of system administration through shell-command examples for non-developers."
I am not sure I would say it’s spammy-looking, but there is something I don’t like about it.
I bought debianhandbook.(com|net|org) (without hyphen) and filed a bug report against debian-handbook asking if they would like me to redirect the three domains or transfer them to the webmaster of debian-handbook.info.
