| bool "Use custom config file" |
| help |
| Select this option to use a custom ubinize configuration file, |
| rather than the default configuration used by Buildroot (which |
| defines a single dynamic volume marked as auto-resize). |
| Passing a custom ubinize configuration file allows you to |
| create several volumes, specify volume types, etc. |
| |
| As a convenience, buildroot replaces the string |
| "BR2_ROOTFS_UBIFS_PATH" with the path to the built ubifs file. |
| So the volume defined for the root filesystem can specify the |
| image path as: image=BR2_ROOTFS_UBIFS_PATH |
| |
| Buildroot also replaces the string "BINARIES_DIR" with the |
| value of $(BINARIES_DIR), so that it is possible to reference |
| other build artefacts (e.g. to include the kernel in a UBI |
| volume). |
