# # For a description of the syntax of this configuration file, # see scripts/kbuild/config-language.txt. # menu "Archival Utilities" config CONFIG_AR bool "ar" default n help ar is an archival utility program used to create, modify, and extract contents from archives. An archive is a single file holding a collection of other files in a structure that makes it possible to retrieve the original individual files (called archive members). The original files' contents, mode (permissions), timestamp, owner, and group are preserved in the archive, and can be restored on extraction. The stored filename is limited to 15 characters. (for more information see long filename support). ar has 60 bytes of overheads for every stored file. This implementation of ar can extract archives, it cannot create or modify them. On an x86 system, the ar applet adds about XXX bytes. Unless you have a specific application which requires ar, you should probably say N here. config CONFIG_FEATURE_AR_LONG_FILENAMES bool " Enable support for long filenames (not need for debs)" default n depends on CONFIG_AR help By default the ar format can only store the first 15 characters of the filename, this option removes that limitation. It supports the GNU ar long filename method which moves multiple long filenames into a the data section of a new ar entry. config CONFIG_BUNZIP2 bool "bunzip2" default n help bunzip2 is an compression utility using the Burrows-Wheeler block sorting text compression algorithm, and Huffman coding. Compression is generally considerably better than that achieved by more conventional LZ77/LZ78-based compressors, and approaches the performance of the PPM family of statistical compressors. The BusyBox bunzip2 applet is limited to de-compression only. On an x86 system, this applet adds about XXX bytes. Unless you have a specific application which requires bunzip2, you should probably say N here. config CONFIG_CPIO bool "cpio" default n help cpio is an archival utility program used to create, modify, and extract contents from archives. cpio has 110 bytes of overheads for every stored file. This implementation of cpio can extract cpio archives created in the "newc" or "crc" format, it cannot create or modify them. Unless you have a specific application which requires cpio, you should probably say N here. config CONFIG_DPKG bool "dpkg" default n help dpkg is a medium-level tool to install, build, remove and manage Debian packages. This implementation of dpkg has a number of limitations, you should use the official dpkg if possible. config CONFIG_DPKG_DEB bool "dpkg_deb" default n help dpkg-deb packs, unpacks and provides information about Debian archives. This implementation of dpkg-deb cannot pack archives. Unless you have a specific application which requires dpkg-deb, you should probably say N here. config CONFIG_FEATURE_DPKG_DEB_EXTRACT_ONLY bool " extract only (-x)" default n depends on CONFIG_DPKG_DEB help This reduced dpkg-deb to the equivalent of "ar -p <deb> data.tar.gz | tar -zx". However it saves space as none of the extra dpkg-deb, ar or tar options are needed, they are linked to internally. config CONFIG_FEATURE_DEB_TAR_GZ bool " gzip debian packages (normal)" default y if CONFIG_DPKG || CONFIG_DPKG_DEB depends on CONFIG_DPKG || CONFIG_DPKG_DEB help This is the default compression method inside the debian ar file. If you want compatability with standard .deb's you should say yes here. config CONFIG_FEATURE_DEB_TAR_BZ2 bool " bzip2 debian packages" default n depends on CONFIG_DPKG || CONFIG_DPKG_DEB help This allows dpkg and dpkg-deb to extract deb's that are compressed internally with bzip2 instead of gzip. You only want this is your are creating your own custom debian packages that use an internal control.tar.bz2 or data.tar.bz2. config CONFIG_GUNZIP bool "gunzip" default n help Please submit a patch to add help text for this item. config CONFIG_FEATURE_GUNZIP_UNCOMPRESS bool " Uncompress support" default n depends on CONFIG_GUNZIP help Please submit a patch to add help text for this item. config CONFIG_GZIP bool "gzip" default n help Please submit a patch to add help text for this item. config CONFIG_RPM2CPIO bool "rpm2cpio" default n help Converts an RPM file into a CPIO archive. config CONFIG_RPM bool "rpm" default n help Mini RPM applet - querys and extracts config CONFIG_TAR bool "tar" default n help tar has at least 512 bytes of overheads for every stored file. Please submit a patch to add help text for this item. config CONFIG_FEATURE_TAR_CREATE bool " Enable archive creation" default y depends on CONFIG_TAR help Please submit a patch to add help text for this item. config CONFIG_FEATURE_TAR_BZIP2 bool " Enable -j option to handle .tar.bz2 files" default n depends on CONFIG_TAR help Please submit a patch to add help text for this item. config CONFIG_FEATURE_TAR_EXCLUDE bool " Enable -X and --exclude options (exclude files)" default n depends on CONFIG_TAR help Please submit a patch to add help text for this item. config CONFIG_FEATURE_TAR_GZIP bool " Enable -z option" default y depends on CONFIG_TAR help Please submit a patch to add help text for this item. config CONFIG_FEATURE_TAR_OLDGNU_COMPATABILITY bool " Enable support for old tar header format" default N depends on CONFIG_TAR help This option is required to unpack archives created with in the old GNU format, help to kill this old format by repacking your ancient archives with the new format. config CONFIG_FEATURE_TAR_GNU_EXTENSIONS bool " Enable support for some GNU tar extensions" default y depends on CONFIG_TAR help With this option usybox supports the GNU long filename and linkanmes. config CONFIG_FEATURE_UNARCHIVE_TAPE bool " Enable tape drive support" default n depends on CONFIG_TAR || CONFIG_CPIO help I dont think this is needed anymore. config CONFIG_UNCOMPRESS bool "uncompress" default n help Please submit a patch to add help text for this item. config CONFIG_UNZIP bool "unzip" default n help Please submit a patch to add help text for this item. endmenu
