Then when you run `xmnt boot`, the tool will look for encryption key according
|
||||||
|
to the UUID of `/dev/nvme0n1p2`, read the key, call `gpg --decrypt` to decrypt
|
||||||
|
the key when necessary, then use the key to open `/dev/nvme0n1p2`, and mount it
|
||||||
|
on `/boot`.
|
||||||
|
|
||||||
|
Directories for storing encryption keys are defined in
|
||||||
|
`$XDG_CONFIG_HOME/xmnt/xmnt.yml`. The tool will recursively search these
|
||||||
|
directories for keys.

You can also use it without defining presets. See `--help` for detailed usage.
