We used to use hardlinks, but dropped it. I believe we dropped it to avoid requiring a complete mirror of every APT source we use during building. Not sure if I remember it correctly, thought. It might also have been because we ran out of disk space when we started building more architectures and variants. > With the recent deployment of the ataboy2, donated by usit. space is > no longer a issue. Note that speed is an issue, though. The ataboy is slower than internal disks, and we had problems earlier with IO before I was able to move everything used during building to internal disks, and everything else to the ataboy. > we can also consider merge the 4 home area's into a single one. I would strongly recommend against this one, as it would allow users to break the automatic build by filling up the partition, and make it harder to track how much space the cinelerra people are using compared to the debian edu people. > And using hardlinking should mean faster builds. How much faster? I believe we have quite quick builds already, and most of the time is spent doing MD5 sums of the packages and final images, so I doubt hardlinking will have that much effect.
