Linux desktops (fedora 11), so I've found this compatible substitute,
as Password Safe is Windows-only.

But first, I had to install wxWidgets, which was easy enough:
sudo yum install wxWidgets
then another 9.5Mb installation later, created a launcher for the app,
pointed to the loxomo.py file, then voila.
The interface seems a bit limited, and you don't have options like
changing the encryption method or the rules it uses for password
generation but it's functional enough. I'll see how it goes in the
next few days.
