Allow me to explain. There was an issue with copying the .git folder to every
host, we literally don't have the space for that and I wonder what happens when
these files grow by a few hundred k. I had put in the symlink, but our
replicator script was chocking on it. Thus I've resorted to not only using a
symlink, but also removing it when not in use. Correcting these issues is
lower priority then making the logs have all the information they need.
Merging has been done when edits are needed ASAP and git becomes an after
thought. I've done pushes from the live files too, though it is something that
happens after an emergency.
I know I've got a rather strange environment, most of it surprises me as well.
