- Common code doing git cloning and updating. - Fixes reseting and repatching of systemd repo if patches change. - Simplifies the git repo refreshing - instead of using files for remembering the current SHA-sum inside some obscure directory structure, we use the git config. - The simplification eliminates some files and directories with names depending on the configure flags. This will help to make sure that "make clean" is independent from the configure flags (as the directory names inside the "revs" directory were dependent on configure flags like --with-stage1-systemd-src).

# This file refreshes the given repository. If new changes are

|
|
# (something like initial clone).
