1)Why does the Getting Started documentation still say that the xz package is a requirement for installing Exherbo? Since version 1.22, tar has supported xz compression/decompression via the J option. Therefore, in the installation procedure, the line “unxz -c *.tar.xz | tar xpf -“ could be replaced with “tar xpJf *.tar.xz”, eliminating the xz dependency.
The -J flag just allows the use of the xz program as a filter. `tar` doesn't actually contain any support for the compression format internally. You still need xz itself to actually process xz-compressed tarballs.
