# configctl
a simple wrapper around fuse-overlayfs to manage multiple config changesets

# Why?
i have an unhealthy relationship with overlayfs. i also like to easily change my desktop themes without a bunch of symlink swapping

# Requirements
* fuse-overlayfs
* systemd

# Usage

```sh
configctl <changeset> [unmount]
```

by default, the configctl expects the base configuration set to exist in `$XDG_DATA_HOME/config/base` (usually `~/.local/share/config/base`) and the changesets to exist in `$XDG_DATA_HOME/config/changeset`. changes while the configuration is mounted will be written to `$XDG_STATE_HOME/config/{<changeset>,.work_<changeset>}`

```sh
configctl my_config
```

executing the previous command will do the following
* search for `$XDG_DATA_HOME/config/changeset/my_config`
* create the following directories if they don't already
  * `$XDG_STATE_HOME/config/my_config`
  * `$XDG_STATE_HOME/config/.work_my_config`
* create a service file in `$XDG_CONFIG_HOME/systemd/user/my_config-automount.service`
* mount the base config and the selected changeset

enabling the service file will mount the config on next user login

# Issues
while technically supported, it's not possible to change or unmount a changeset once mounted. this is because the mount will become immediately busy, preventing `fusermount` from being able to unmount it.
