Re: Debian at GSI

Hi Christopher,

That is indeed a great story of success for the Debian project.  Thank
you for sharing!  I wonder if there is any representative page at gsi.de
which would mirror your statement?

Googling for debian on gsi.de comes back with lots of links, including
such as
Upgrade to Debian 2.0/Kernel 2.1.125  Thomas Neff: October 16, 1998

providing pieces of evidence to your description ;)  but I hoped there
could be some good summary somewhere.

Basically the job description covers all our tasks from high-level configuration management with Chef to fiddling with broken hardware in case of an urgent emergency (this became more and more seldom during the years). The new position will probably focus a lot on monitoring, which did not grow fast enough with the growth of the farm during the last years.
