prune: strategies for linked checkouts
(alias R=$GIT_COMMON_DIR/worktrees/<id>)
- linked checkouts are supposed to keep its location in $R/gitdir up
to date. The use case is auto fixup after a manual checkout move.
- linked checkouts are supposed to update mtime of $R/gitdir. If
$R/gitdir's mtime is older than a limit, and it points to nowhere,
worktrees/<id> is to be pruned.
- If $R/locked exists, worktrees/<id> is not supposed to be pruned. If
$R/locked exists and $R/gitdir's mtime is older than a really long
limit, warn about old unused repo.
- "git checkout --to" is supposed to make a hard link named $R/link
pointing to the .git file on supported file systems to help detect
the user manually deleting the checkout. If $R/link exists and its
link count is greated than 1, the repo is kept.

Use `git rev-parse --git-path` to get the final path. +When you are done with a linked working tree you can simply delete it. +You can clean up any stale $GIT_DIR/worktrees entries via `git prune +--worktrees` in the main or any linked working tree. + +If you move a linked working directory to another file system, or +within a file system that does not support hard links, you need to run +at least one git command inside the linked working directory +(e.g. `git status`) in order to update its entry in $GIT_DIR/worktrees +so that it does not get automatically removed. + +To prevent `git prune --worktrees` from deleting a $GIT_DIR/worktrees +entry (which can be useful in some situations, such as when the +entry's working tree is stored on a portable device), add a file named +'locked' to the entry's directory. The file contains the reason in +plain text. For example, if a linked working tree's `.git` file points +to `/path/main/.git/worktrees/test-next` then a file named +`/path/main/.git/worktrees/test-next/locked` will prevent the +`test-next` entry from being pruned.
