[Beuc]

++added:


Currently here are the subsystems we use::

 # vserver-stat
 CTX   PROC    VSZ    RSS  userTIME   sysTIME    UPTIME NAME
 101     42 773.5M 267.7M   7d12h24   3d14h16  36d10h29 internal
 102      4  10.8M   2.8M  13h46m09   1h36m02  35d13h15 accounts
 103     32   3.1G 293.8M   8d21h07   1d14h54  36d10h29 frontend
 104    122   1.3G   280M  31d10h54   8d15h36  36d10h29 vcs-noshell
 105     91 836.6M  94.1M  15h11m59   3h04m16  36d10h29 sftp
 106      3   7.2M   2.3M  45m33s75  18m00s80  36d10h29 builder

* frontend: Savane frontend, the web interface at sv.gnu.org and sv.nongnu.org
* accounts: replicates the database to system (Unix) accounts; /etc/passwd and 
/etc/group are regularly copied (overwrite) to vcs-noshell and sftp
* vcs-noshell: public services that are accessed through a restricted shell: 
CVS, Git, SVN, Hg, with their respective web browsing apps
* sftp: public services that are accessed through a restricted shell and allow 
users to write files anywhere they want (using SFTP/SCP/rsync): download, bzr, 
GNU Arch, and an Apache instance to access them
* internal: runs internal services, like the MySQL database, the Exim MTA (with 
From: and sender rewrite), a Debian mirror. There's also a public Cacti 
instance there.
* builder: used to rebuild software, Debian packages or kernels. It's separate 
so there's no problem with installing dependencies, testing them, etc. There's 
a pbuilder (cowbuilder) ready for Etch+backports rebuilds.
* and of course, the host (not a vserver) where admins can log in. There's an 
unused by functional chroot'd DNS setup and a Apache with a "Savannah downtime" 
frontpage
