[clo-devel] upgrading: how do you (want to) use cl.net? [detected: very large home directories]

Ok. That's probably not too practical indeed. I've contacted some of
the biggest users. Cleaning out some of the old cruft from their home
directories made /home go down to a usage of 60%. With that
percentage, I know our scaling doesn't need adapting. I'm considering
how to deal with the situation for the future. On one hand I think
installing a quota of 200MB on the /home directory of each user
separately sounds sane and not too restrictive. Otoh, maybe with some
monitoring, we can resolve the situation in a less strict way: after
all, there's the request at sign-up to use the resources of cl.net
sparingly (and exclusively at the service of Common Lisp and its
community).

While I think this is a great idea, I'm not sure cl.net is the place
for that. The combined services running on the machine are claiming
quite a bit of processing power and these build farms can really
impact the responsiveness of other services. I don't think we want
that for our other services.

Ok. Well, then I guess we'll have to keep running anonymous CVS access
through cvsd (pserver).

Bye,


Erik.
