# # Configuration for initramfs # config INITRAMFS_SOURCE string "Initramfs source file(s)" default "" help This can be either a single cpio archive with a .cpio suffix or a space-separated list of directories and files for building the initramfs image. A cpio archive should contain a filesystem archive to be used as an initramfs image. Directories should contain a filesystem layout to be included in the initramfs image. Files should contain entries according to the format described by the "usr/gen_init_cpio" program in the kernel tree. When multiple directories and files are specified then the initramfs image will be the aggregate of all of them. See for more details. If you are not sure, leave it blank. config INITRAMFS_ROOT_UID int "User ID to map to 0 (user root)" depends on INITRAMFS_SOURCE!="" default "0" help This setting is only meaningful if the INITRAMFS_SOURCE is contains a directory. Setting this user ID (UID) to something other than "0" will cause all files owned by that UID to be owned by user root in the initial ramdisk image. If you are not sure, leave it set to "0". config INITRAMFS_ROOT_GID int "Group ID to map to 0 (group root)" depends on INITRAMFS_SOURCE!="" default "0" help This setting is only meaningful if the INITRAMFS_SOURCE is contains a directory. Setting this group ID (GID) to something other than "0" will cause all files owned by that GID to be owned by group root in the initial ramdisk image. If you are not sure, leave it set to "0". config RD_GZIP bool "Support initial ramdisks compressed using gzip" depends on BLK_DEV_INITRD default y select DECOMPRESS_GZIP help Support loading of a gzip encoded initial ramdisk or cpio buffer. If unsure, say Y. config RD_BZIP2 bool "Support initial ramdisks compressed using bzip2" default y depends on BLK_DEV_INITRD select DECOMPRESS_BZIP2 help Support loading of a bzip2 encoded initial ramdisk or cpio buffer If unsure, say N. config RD_LZMA bool "Support initial ramdisks compressed using LZMA" default y depends on BLK_DEV_INITRD select DECOMPRESS_LZMA help Support loading of a LZMA encoded initial ramdisk or cpio buffer If unsure, say N. config RD_XZ bool "Support initial ramdisks compressed using XZ" depends on BLK_DEV_INITRD default y select DECOMPRESS_XZ help Support loading of a XZ encoded initial ramdisk or cpio buffer. If unsure, say N. config RD_LZO bool "Support initial ramdisks compressed using LZO" default y depends on BLK_DEV_INITRD select DECOMPRESS_LZO help Support loading of a LZO encoded initial ramdisk or cpio buffer If unsure, say N. config RD_LZ4 bool "Support initial ramdisks compressed using LZ4" default y depends on BLK_DEV_INITRD select DECOMPRESS_LZ4 help Support loading of a LZ4 encoded initial ramdisk or cpio buffer If unsure, say N.
