1config FS_SQUASHFS 2 bool "Enable SquashFS filesystem support" 3 select ZLIB_UNCOMPRESS 4 help 5 This provides support for reading images from SquashFS filesystem. 6 Squashfs is a compressed read-only filesystem for Linux. 7 It uses zlib, lz4, lzo, or xz compression to compress files, inodes 8 and directories. Squashfs is intended for general read-only 9 filesystem use, for archival use (i.e. in cases where a .tar.gz file 10 may be used), and in constrained block device/memory systems (e.g. 11 embedded systems) where low overhead is needed. 12
