Thanks Ralf,

I went for CentOS 6.3 since this boxen will be replacing a Ubuntu system that has been doing backup SVN server duty as well.

The install went quite quickly, though there are a few parts of the getting started wiki that reminded me of "add enough salt". 

I also installed CentOS on my MacBook under Fusion and RTEMS compiled in about 3 minutes compared to my regular overnight batch job that MSYS gave me.

So far, much better.

Due to its nature, the price is "high updates/upgrade rates", its short life time and occasionally have to cope with "leading edge warts".

Using it as development platform is possible until the point, when the age of the components CentOS consists of starts showing (No ABI/ABI-changes) and renders things complicated. Also, due to CentOS being based on a non-Free Linux distribution, getting bugs fixed is hard to achieve.
