Happy new year everyone. By posting something now I make sure I will post at least one this year :)
During Christmas I have been busy hacking an automated rebuild of Mageia.
I am using a single machine, and building only on x86_64. The machine has 12 cores and 32G ram so I am building 6 packages in parallel with -l12 -j12 on tmpfs, with some swap to prevent very large packages to break the build of others. It takes about 30 hours to build just under 11000 packages, creating a clean chroot each time.
I was happily surprised by the results of the first rebuild, 90.1% success (9845 packages built successfuly), and even more with the second (93.3%) after fixing a few packages breaking many others. I was less happy when the results went down in the recent runs (new version of rpm, new version of automake breaking 304 packages by removing AM_CONFIG_HEADER, %libexec changed to be different from %lib in our rpm config...), but at least we have the number, and better, the list of packages to fix!
Current main problems and limitations:
Ah, and I will be attending FOSDEM as usual, so see you near some Belgian beers!
