I got to exercise my newfound ASF Infrastructure powers for the first time today, by upgrading the httpd install that runs http://svn.apache.org/ (and http://cvs.apache.org/ for what it's worth) to version 2.2.0. The main http://www.apache.org/ instance has been running 2.2.0 (well, 2.1.10, which is just 2.2.0 with a slightly different version number) for a while now, so I don't anticipate any problems, but I was still a little nervous since it was my first time doing something like this.
For the curious, the only reason this hadn't happened yet was that upgrading this httpd install involves rebuilding mod_dav_svn and mod_authz_svn (since the MMN changed between the last version and this one) and nobody had managed to find the free time to do it.
Anyway, everything seems to be working just fine, but if you notice any problems please feel free to drop me a line.
