**upgrades no longer touch the config or the keydir**
When you first install gitolite, the easy install script has to do two
*distinct* things:
* install the software
* create and seed the gitolite-admin repo with a minimum config file
and the newly created pubkey
That's fine for an install, because nothing exists yet anyway.
Subsequent invocations of the script should only do the first task (so
that gitolite itself can be upgraded), and not attempt to fiddle with
the config file and pubkeys.
Unfortunately, until now I had not been separating these two activities
cleanly enough. For instance, the commit message for 8e47e01 said:
IMPORTANT: we assume that $admin_name remains the same in an upgrade
-- that's how we detect it is an upgrade! Change that name or his
pubkey, and you're toast!
Ouch!
So now I decided to clean things up. The "Usage" message tells you
clearly what to do for an upgrade.
Should have been like this from the beginning, but hey we got there
eventually :)
----
Code-wise, this is a major refactor of the easy install script. It uses
an old forgotten trick to get forward refs for bash functions ;-) and in
the process cleans up the flow quite a bit.
- added comments to easy install to help do it manually
- README: some stuff moved to tips doc, brief summary of extras
(over gitosis) added
- INSTALL: major revamp, easy install and manual install,
much shorter and much more readable!
plus other docs changed as needed, and updated the tips doc to roll in
some details from "update.mkd" in the "ml" branch
- install is even clearer now (I hope!), esp to people with root
access who seem to expect something else :)
- used path vars (from ~/.gitolite.rc) more consistently, and
- added refeerences to ~/.gitolite.rc for resolving them
