========================
NAME
----
cdist-type__borg_repo - Configure a borg repository on host
DESCRIPTION

Initializes a borg repository at the location specified in the

Currently, only `none` and `repokey` are supported as encryption modes;
`repokey` requires the `passphrase` argument to be given. The default is
`none`.
REQUIRED PARAMETERS
-------------------
encryption
The encryption to use.
OPTIONAL PARAMETERS
-------------------
passphrase
The passphrase to encrypt the keyfile with.
BOOLEAN PARAMETERS
------------------
append-only
If the repository is append-only
