is a pool of interactive Debian
-based computers inside the Network
at the CRYRING cave and its electronics containers. The network is separated from the main GSI computer networks and can be accessed only through a limited number of proxy hosts. User profiles inside the
pool are roamed and you should find a equivalent work environment on any of these computers.
Please be advised:
- The pool is still largely in development. Apologies in advance, should you observe any hiccups!
- We do not create backups of your data. This is entirely your own responsiblity!
- Should you be missing essential software, please let us know.
- Disk access is limited by a (failry adequate) quota.
We do our best to track the stable
release of Debian and to keep all systems in sync.
