Can someone tell me what this: /boot/home/config/add-ons/kernel/drivers/bin/virtualdrive does in MY home tree ? it doesn't belong to here. If it's neded for the tests, as suggests src/tests/kits/storage/virtualdrive/Jamfile then please add a 'jam test' rule, but do NOT install things on the build machine without telling the user. No wonder now why this box had problems recently if everything gets installed without notification. (like apps killing themselves, bdb not even launching... not sure it's related, but if I want this troubleshooted quickly I don't need interferences from something else). At least provide a 'jam clean' which really removes everything, including things that were isntalled everywhere. I hope there aren't any other binaries that puts itself anywhere it isn't intended to ? :p François.
