Talking to halfline today and yesterday I decided to spend a little time playing with this for another project.
mockchain.py [options] chrootname file.src.rpm [file1.src.rpm] [file2.src.rpm] ... Builds a series of srpms in mock one at a time. After each successful build of a package it adds the resulting packages to a local repo which are available to the next package to satisfy buildreqs. options: -c - continue on package build failure - by default it will exit if a package fails to build. set this if you wish it to try and continue for the rest of the packages. -l path - set the path to put the results/repo in. This path needs to be somewhere accessible to users other than you for reading as the mock process doesn't run as you. This does not try to sort the packages by build order b/c that is too much effort and not obviously doable with the buildreq information we have. The build process when you use -l is idempotent so a package which has already been successfully built will not be built again. If you want to force the rebuild of a package which has been built successfully simply remove the 'success' file from the dir with the package results in it.
