The metadata is not compressed, but is expressed in a terse representation that is more space-efficient than conventional file systems. + +The file system is intentionally read-only to simplify its design; random write access for compressed files is difficult to implement. cramfs ships with a utility (*mkcramfs*(8)) to pack files into new cramfs images. + +File sizes are limited to less than 16 MB. + +Maximum file system size is a little under 272 MB. (The last file on the file system must begin before the 256 MB block, but can extend past it.) + +== ARGUMENTS + +The _directory_ is simply the root of the directory tree that we want to generate a compressed filesystem out of. + +The _file_ will contain the cram file system, which later can be mounted. + +== OPTIONS + +*-v*:: +Enable verbose messaging. + +*-E*:: +Treat all warnings as errors, which are reflected as command exit status. + +*-b* _blocksize_:: +Use defined block size, which has to be divisible by page size. + +*-e* _edition_:: +Use defined file system edition number in superblock. + +*-N* _big, little, host_:: +Use defined endianness. Value defaults to _host_. + +*-i* _file_:: +Insert a _file_ to cramfs file system. + +*-n* _name_:: +Set name of the cramfs file system. + +*-p*:: +Pad by 512 bytes for boot code. + +*-s*:: +This option is ignored. Originally the *-s* turned on directory entry sorting. + +*-z*:: +Make explicit holes. + +include::man-common/help-version.adoc[] + +== EXIT STATUS + +*0*:: +success +*8*:: +operation error, such as unable to allocate memory + +== SEE ALSO + +*fsck.cramfs*(8), +*mount*(8) + +include::man-common/bugreports.adoc[] + +include::man-common/footer.adoc[] + +ifdef::translation[] +include::man-common/translation.adoc[] +endif::[] -- cgit v1.2.3
