Wheezy is installed on a virtualbox machine (host is windows xp, guest is 
wheezy).

I saw nothing relevant but the "Filesystem is NOT clean" message, but 
sure, I'll add it as soon as I can access the VM on the afternoon, now 
I'm at work.

ReiserFS is a filesystem that I've been using since my first linux 
installation (that's 8 years ago) and have been working rock solid on all 
the machines (servers, workstations and desktop computers). True is that 
all the machines are properly backed by UPS units but this filesystem has 
been recovering very well even when the computers had to be reseted or 
powered down in a not so nicely manner.

In brief, I like ReiserFS and the only thing that refrains me for keeping 
using it is that, AFAIK, nowadays is only receiving patches (no new 
features) in the mainline kernel.
