posix tar archive (GNU) archive format

[M0Rf30]

Introduce the format you are requesting.

While both POSIX tar and GNU tar serve the same fundamental purpose of archiving files, GNU tar extends the functionality of the POSIX standard with additional features, support for larger files, and enhanced metadata handling.

What do YOU use this format for?

Most Linux distributions (such as Arch Linux, Ubuntu, Fedora, CentOS, and Debian) come with GNU tar pre-installed as the default archiving tool. It is used for creating and extracting tar archives in software packaging, backups, and file management.

I will use it to generate .deb internal archives (control.tar and data.tar)

What is the format's conventional file extension(s)?

.tar

Please link to the format's formal or official specification(s).

Which Go libraries could be used to implement this format?

https://pkg.go.dev/archive/tar

Seems that official archive/tar module is able to handle this archive format
