post-apply hook or something like that

Hello fellow gits,

I try to insert metastore into my workflow and i wonder if i could get
the following scenario working:

(1) cd /etc/ && git-init-db # start gittify etc-directory
(2) git commit -a # fire up first commit
(3) metastore -s # save current state of permissions and ownerships
(4) git commit -a # commit the changes
(5) chown nobody bash/<somefile> # change ownership
(6) git commit -a # with the pre-commit shipped with metastore this is tracked
(7) git reset --hard HEAD^1 # go back one step
(8) git reset --hard <former-sha1-sum> # go forward again
(9) metastore -a # apply the changes from last commit

what i was wondering, is it possible, to get a metastore -a
automatically after checking out something?

Greetings
Nicolas
