I do use "gdm" to boot into "jwm"; the (Debian) description of "jwm" 

 JWM is a window manager for the X11 Window System. JWM is written in C 
and uses only Xlib and (optionally) the shape extension and libXpm. It 
can support some MWM, GNOME, and WM Spec hints. The menu configuration 
files are managed in XML format.

 Compared to other light WM, like Fvwm95, the Jwm consumes about twice 
less memory while providing the same WM functionality.

My current system is just a simple Lenny desktop; the only upgrade path 
pointed to http://security.debian.org/ lenny/updates.  Does the following 
tell you enough:

  Kernel  Linux 2.6.26-2-486 (i686)

One of my many deviations. I use lilo; I find it easier to configure. I 
am hoping that I will have made the correct adjustments to my /etc/
lilo.conf before I reboot.

According to the release notes, that includes the Linux kernel!  Hence I 
am checking at each step on the way.

Not if you source them from the US.  I have received the DVDs for Debian 
6.0.0 about one week ago; Debian 6.0.1 has been released today.  I 
normally run "security upgrades" every week; I rely on the DVDs for all 
other packages.

That puts the nails in the coffin!
The alternative upgrade option is too frightening to contemplate!

So far, I have crashed at Stage 1!

After consulting the "release notes", it appears that their suggested 
size for "Cache-Limit" in "/etc/apt/apt.conf" is too small for Squeeze.  
By trebling that size, I successfully added the 8 DVDs to my 
"sources.list" and had their presence recognised by "apt-get" and 

Unscrambling this mess kept me entertained for an afternoon; I am now 
catching my breath before starting on the next stage of the "dist-
