Inspired by the OP I devised a slightly modified method for cataloguing my optical media library.
The goal is having a main git-annex repo tracking what's on HDD, while adding the optical media as one-time remotes for location tracking and easy future inspection of their contents without having to physically insert the disc in the drive and mounting it.
The current contents of the HDD and the contents of the total set of the optical discs are not a 1:1 match, both have files not present in the other.
Current plan:
1. copy already burnt discs to a directory on disk and create a git-annex repo with the same configuration as the main catalogue repo, using the disc label as description:
```
git annex init disc_label && git annex config --set annex.dotfiles true && git config annex.backend MD5 && git config annex.gitaddtoannex false
```
2. add the optical disc repo as remote in the main repo:
```
git remote add CD1 /mnt/CD1/ && git annex sync --no-push -jobs=cpus && git annex sync --cleanup && git remote remove CD1
```
3. create a branch for easily \"mounting\" each disc with git checkout without needing to
```git log --oneline | grep disc_label```
for finding the relevant commit hash:
```
git branch CD1 XXXXXXXXXX
```
4. edit working tree as desired, then override git-annex sync's automatic commit:
```
git add . && git commit --quiet --amend --message=\"add CD1\"
```
5. repeat for other discs
The main repo should end up looking like so, each optical disc \"dangling\" from the main branch that tracks the HDD contents:
```
$ git log --graph --oneline
* XXXXXXXXXX (HEAD -> master) add DVD1
|\
| * XXXXXXXXXX (DVD1) DVD1
* XXXXXXXXXX add CD1
|\
| * XXXXXXXXXX (CD1) CD1
* XXXXXXXXXX init
```
and any file given as argument to ```git annex whereis``` should be easily traceable:
```
$ git-annex whereis file
whereis file (4 copies)
XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX -- HDD [here]
XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX -- CD1
XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX -- DVD1
XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX -- BD1
ok
```
Seems good enough for me but considering I can barely wrap my head around all that git and git-annex are capable of I'm posting here hoping for a sanity check that this solution does work as expected and/or suggestions for improvements before fully committing to it.
