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.

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.

bool "bunzip2"

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.

cpio is an archival utility program used to create, modify, and extract

contents from archives.

This implementation of cpio can extract cpio archives created in the

This reduced dpkg-deb to the equivalent of "ar -p <deb> data.tar.gz | tar -zx".

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.
