cache-fs
|
|
--------
|
|
|
|
caching fs to use over immutable network filesystems
|
|
|
|
The use-case is something like your Steam Deck has a large directory of roms mounted over NFS, but if you disable wifi,
|
|
you want the roms you've already played still available.
|
|
|
|
This basically bind-mounts your NFS share over a path of your choosing, except it caches all file attributes/paths
|
|
forever, and copies the files you open to your cache directory. When you access that file again it doesn't access the
|
|
remote server at all. So if your remote (say NFS) server is not available, you can still play the games.
|
|
|
|
If you add/change files to your remote, you must delete `/local/cache/dir/cache-fs.tree` and remount.
|
|
|
|
Usage
|
|
-----
|
|
|
|
This assumes you install the `cache-fs` binary as `mount.cachefs`, then you can use it in /etc/fstab etc
|
|
```
|
|
mount -t cachefs -o cache_dir=/local/cache/dir /remote/dir/to/cache /where/you/want/it/mounted
|
|
```
