`image.repart.mkfsOptions`

Specify extra options for created file systems. The specified options are converted to individual environment variables of the format SYSTEMD_REPART_MKFS_OPTIONS_<FSTYPE>.

See upstream systemd documentation for information about the usage of these environment variables.

The example would produce the following environment variable:

The store paths to include in the partition. Type: list of path

Default

[ ]

Declared by: https://github.com/nixos/nixpkgs/blob/master/nixos/modules/image/repart.nix

`image.repart.partitions.<name>.stripNixStorePrefix`
