BUNDLE SUPPORT
(1) For each repo in gitolite.conf for which you want bundle support (or
'@all', if you wish), add the following line:
option bundle = 1
Or you can say:
option bundle.ttl = <number>
A bundle file that is more than <number> seconds old (default value
86400, i.e., 1 day) is recreated on the next bundle request. Increase
this if your repo is not terribly active.
Note: a bundle file is also deleted and recreated if it contains a ref
that was then either deleted or rewound in the repo. This is checked
on every invocation.
(2) Add 'rsync' to the ENABLE list in the rc file

BUNDLE SUPPORT
Admins: see src/commands/rsync for setup instructions
Users:
rsync -P git@host:repo.bundle .
# downloads a file called "<basename of repo>.bundle"; repeat as
# needed till the whole thing is downloaded
git clone repo.bundle repo
cd repo
git remote set-url origin git@host:repo
git fetch origin # and maybe git pull, etc. to freshen the clone
