Running "git init" in an empty directory consumes about 100k of diskspace
on the machine I am typing this on, and you should be able to share most
of them (except one 41-byte file that is the branch tip ref) when you
track many files inside a single directory by using a single repository,
one branch per file (or "one set of branches per file") model.
the reason to use seperate repos is to ease the work involved if you need to
move that file (and it's repo) elsewhere.
Precisely. The one-repo-per-file is just the simplest and most
flexible solution. But yes, I have to admit I hadn't looked into disk
usage, and indeed we should try and squeeze this as much as possible.
with the git directory being under .zit, would it be possible to link the
things that are nessasary togeather?
I'm not sure about _which_ files could be shared.
hmm, looking at this in more detail.
about 44K of diskspace is used by the .sample hook files, so those can be
removed
Exactly. I'm setting up zit to prepare its repos to a more compact
form, and getting rid of hooks and description is the first step.
the remaining 56K is mostly directories eating up a disk block

how many of these are _really_ nessasary?
For starters, I'm wondering if setting core.preferSymlinkRefs would be
useful here. Does it break sometihng?
tags, info, hooks, branches, and description could probably be skipped for
the common zit case, as long as they can be created as needed.
It seems that tags, hooks, branches and description can be done with.
do you mean 'can be done away with'?
info contains exclude which is rather essential,
is it? by default everything in this file is commented out. And with you
only adding files explicitly why would it ever need to excluded anything?
