The main reason why git uses this is that the "index" (git equivilant of
the CVS/*) resides in 1 place instead of in each directory. So, if you
have multiple working directories sharing a single .git, you get them
tromping on each others "index".
That said, you can symlink almost everything *inside* .git to other
repositories.
For instance, if you had the "Reference" repository I shows last time,
instead of doing the "git clone", you could do:
#Make a new REL8_2_STABLE working areamountie@pumpkin:~/pg-work$ REF=$(pwd)/PostgreSQL.gitmountie@pumpkin:~/pg-work$
mkdirREL8_2_STABLEmountie@pumpkin:~/pg-work$ cd REL8_2_STABLE/mountie@pumpkin:~/pg-work/REL8_2_STABLE$ git init
# And now make everything point backmountie@pumpkin:~/pg-work/REL8_2_STABLE$ mkdir .git/refs/remotes && ln -s
$REF/refs/heads.git/refs/remotes/originmountie@pumpkin:~/pg-work/REL8_2_STABLE$ rm -Rf .git/objects && ln -s
$REF/objects.git/objectsmountie@pumpkin:~/pg-work/REL8_2_STABLE$ rmdir .git/refs/tags && ln -s $REF/refs/tags
.git/refs/tagsmountie@pumpkin:~/pg-work/REL8_2_STABLE$rm -Rf .git/info && ln -s $REF/info
.git/infomountie@pumpkin:~/pg-work/REL8_2_STABLE$rm -Rf .git/hooks && ln -s $REF/hooks
This will leave you with an independent config, independent index,
independent heads, and independent reflogs, with a shared "remote"
tracking branches, shared "object" store, shared "tags", and shared
hooks.
And make sure you don't purge any unused objects out of any of these
subdirs, because they don't know that the object might be in use in
another subdir... This warning is the one reason why it's usually
recommended to just use a reference repository, and not have to worry..
