41 config BUSYBOX_CONFIG_AR
43 default n # needs to be improved to be able to replace binutils ar
45 ar is an archival utility program used to create, modify, and
46 extract contents from archives. An archive is a single file holding
47 a collection of other files in a structure that makes it possible to
48 retrieve the original individual files (called archive members).
49 The original files' contents, mode (permissions), timestamp, owner,
50 and group are preserved in the archive, and can be restored on
53 The stored filename is limited to 15 characters. (for more information
54 see long filename support).
55 ar has 60 bytes of overheads for every stored file.
57 This implementation of ar can extract archives, it cannot create or
59 On an x86 system, the ar applet adds about 1K.
61 Unless you have a specific application which requires ar, you should
64 config BUSYBOX_CONFIG_FEATURE_AR_LONG_FILENAMES
65 bool "Support for long filenames (not needed for debs)"
67 depends on BUSYBOX_CONFIG_AR
69 By default the ar format can only store the first 15 characters
70 of the filename, this option removes that limitation.
71 It supports the GNU ar long filename method which moves multiple long
72 filenames into a the data section of a new ar entry.
74 config BUSYBOX_CONFIG_FEATURE_AR_CREATE
75 bool "Support archive creation"
77 depends on BUSYBOX_CONFIG_AR
79 This enables archive creation (-c and -r) with busybox ar.
81 config BUSYBOX_CONFIG_BUNZIP2
85 bunzip2 is a compression utility using the Burrows-Wheeler block
86 sorting text compression algorithm, and Huffman coding. Compression
87 is generally considerably better than that achieved by more
88 conventional LZ77/LZ78-based compressors, and approaches the
89 performance of the PPM family of statistical compressors.
91 Unless you have a specific application which requires bunzip2, you
92 should probably say N here.
94 config BUSYBOX_CONFIG_BZIP2
98 bzip2 is a compression utility using the Burrows-Wheeler block
99 sorting text compression algorithm, and Huffman coding. Compression
100 is generally considerably better than that achieved by more
101 conventional LZ77/LZ78-based compressors, and approaches the
102 performance of the PPM family of statistical compressors.
104 Unless you have a specific application which requires bzip2, you
105 should probably say N here.
107 config BUSYBOX_CONFIG_CPIO
111 cpio is an archival utility program used to create, modify, and
112 extract contents from archives.
113 cpio has 110 bytes of overheads for every stored file.
115 This implementation of cpio can extract cpio archives created in the
116 "newc" or "crc" format, it cannot create or modify them.
118 Unless you have a specific application which requires cpio, you
119 should probably say N here.
121 config BUSYBOX_CONFIG_FEATURE_CPIO_O
122 bool "Support for archive creation"
124 depends on BUSYBOX_CONFIG_CPIO
126 This implementation of cpio can create cpio archives in the "newc"

132 depends on BUSYBOX_CONFIG_FEATURE_CPIO_O
134 Passthrough mode. Rarely used.
136 config BUSYBOX_CONFIG_DPKG
139 select BUSYBOX_CONFIG_FEATURE_SEAMLESS_GZ
141 dpkg is a medium-level tool to install, build, remove and manage
144 This implementation of dpkg has a number of limitations,

159 config BUSYBOX_CONFIG_FEATURE_DPKG_DEB_EXTRACT_ONLY
160 bool "Extract only (-x)"
162 depends on BUSYBOX_CONFIG_DPKG_DEB
164 This reduces dpkg-deb to the equivalent of
165 "ar -p <deb> data.tar.gz | tar -zx". However it saves space as none
166 of the extra dpkg-deb, ar or tar options are needed, they are linked
169 config BUSYBOX_CONFIG_GUNZIP
173 gunzip is used to decompress archives created by gzip.
174 You can use the `-t' option to test the integrity of
175 an archive, without decompressing it.

251 bool "Support for old tar header format"
253 depends on BUSYBOX_CONFIG_TAR || BUSYBOX_CONFIG_DPKG
255 This option is required to unpack archives created in
256 the old GNU format; help to kill this old format by
257 repacking your ancient archives with the new format.
259 config BUSYBOX_CONFIG_FEATURE_TAR_OLDSUN_COMPATIBILITY
260 bool "Enable untarring of tarballs with checksums produced by buggy Sun tar"
262 depends on BUSYBOX_CONFIG_TAR || BUSYBOX_CONFIG_DPKG
264 This option is required to unpack archives created by some old
265 version of Sun's tar (it was calculating checksum using signed
266 arithmetic). It is said to be fixed in newer Sun tar, but "old"
267 tarballs still exist.
