My choice of name was guided by the following:
$ find arch -name '*defconfig*' -print | wc -l 469
When I try baseconfig:
$ find arch -name '*baseconfig*' -print | wc -l 0
Don't get me wrong, you might be correct here. But the thing is that I like being able to specify all tests in one go. That means that I want to still be able to run my current defconfig-based config files (e.g., TREE01) when I get a randconfig-based setup going. So I would like to be able to specify something like:
sh kvm.sh --defconfig pseries_defconfig --configs "TREE01 RAND01"
But perhaps there is a better way to do this.
Thanx, Paul
