1 SQUASHFS 4.3 - A squashed read-only filesystem for Linux
10 Squashfs is a highly compressed read-only filesystem for Linux.
16 Squashfs is intended for general read-only filesystem use, for archival
74 Squashfs filesystems should be mounted with 'mount' with the filesystem type
75 'squashfs'. If the filesystem is on a block device, the filesystem can be
80 Will mount the squashfs filesystem on "/dev/sda1" under the directory "/mnt".
82 If the squashfs filesystem has been written to a file, the loopback device
87 Will mount the squashfs filesystem in the file "image" under
96 As squashfs is a read-only filesystem, the mksquashfs program must be used to
102 Filesystem build options:
112 -no-exports don't make the filesystem exportable via NFS
126 -nopad do not pad filesystem to a multiple of 4K
131 Filesystem filter options:
143 Filesystem append options:
144 -noappend do not append to existing filesystem
153 -recover <name> recover filesystem data using recovery file <name>
155 -info print files written to filesystem
213 files/directories that will form the squashfs filesystem. If a single
215 filesystem will consist of that directory, with the top-level root
219 the specified sources into a single filesystem, with the root directory
233 This will generate a squashfs filesystem with root entries

272 write a new filesystem irrespective of whether an existing filesystem is

368 generate a filesystem similar to a Squashfs 1.x filesystem. It will of course
369 still be a Squashfs 4.0 filesystem but without fragments, and so it won't be
385 added to the filesystem for duplicates. This can result in quicker filesystem
393 3.4 Specifying the UIDs/GIDs used in the filesystem
396 By default files in the generated filesystem inherit the UID and GID ownership
401 file uids/gids in the generated Squashfs filesystem to be root. This allows
405 filesystem to be owned by the specified uid. The uid can be specified either by
409 filesystem to be group owned by the specified gid. The gid can be specified
412 3.5 Excluding files from the filesystem
416 excluded from the output filesystem. The -e option takes the exclude
508 filesystem, where it is wished to avoid archiving /proc, and the filesystem
520 filesystem will add the source items to the existing filesystem. By default,
523 To make this clear... An existing filesystem "image" contains root entries

573 option can be used to recover the filesystem, giving the previously
585 and block devices to be specified and added to the Squashfs filesystem being

725 The -nopad option informs mksquashfs to not pad the filesystem to a 4K multiple.
726 This is performed by default to enable the output filesystem file to be mounted
727 by loopback, which requires files to be a 4K multiple. If the filesystem is
734 Unsquashfs allows you to decompress and extract a Squashfs filesystem without
735 mounting it. It can extract the entire filesystem, or a specific

827 The "-stat" option displays filesystem superblock information. This is
828 useful to discover the filesystem version, byte ordering, whether it has a NFS
829 export table, and what options were used to compress the filesystem, etc.
831 Unsquashfs can decompress all Squashfs filesystem versions, 1.x, 2.x, 3.x and
