I think build information should be kept "forever", because it's nice to 
see progress over time. And I also see some value in keeping not too old 
build artifacts, because it allows me to quickly see what was the 
situation X builds ago.
After a bit of googling, I found that there's a "Discard Old Builds"
option[1][2], which can simply delete all build information based on some 
simple rules.
But there's also a plugin[3] which does exactly what I would like to see. 
One can specify to keep the build information with it, while deleting the 
build artifacts of older builds.
So I think we (I mean someone who has access to jenkins) should install 
and configure that plugin for the critical projects. These are SqueakTrunk 
and ReleaseSqueakTrunk, which use 17GB of disk space at the moment.
