CONFIG_CRAMFS: Compressed ROM file system support

General informations

The Linux kernel configuration item CONFIG_CRAMFS has multiple definitions:

Compressed ROM file system support (cramfs) (OBSOLETE) found in fs/cramfs/Kconfig

The configuration item CONFIG_CRAMFS:

Help text

Saying Y here includes support for CramFs (Compressed ROM File System). CramFs is designed to be a simple, small, and compressed file system for ROM based embedded systems. CramFs is read-only, limited to 256MB file systems (with 16MB files), and doesn't support 16/32 bits uid/gid, hard links and timestamps.

See Documentation/filesystems/cramfs.txt and fs/cramfs/README for further information.

To compile this as a module, choose M here: the module will be called cramfs. Note that the root file system (the one containing the directory /) cannot be compiled as a module.

This filesystem is obsoleted by SquashFS, which is much better in terms of performance and features.

If unsure, say N.
