[pacman] - Libarchive or bsdtar handle compression/decompress tasks?

Doesn't bsdtar handle compression and decompression for makepkg/pacman? In other words, there shouldn't be a need to have component compression/decompression utils such as lrzip installed for this to work, no?

In a clean chroot, I set `PKGEXT='.pkg.tar.lrz'` in /etc/makepkg.conf and intentionally did not install lrzip. I found that makepkg choked when it came time to compress. Same is true when attempting to install foo.tar.lrz via `pacman -U foo.tar.lrz` ... did I miss something?

Yes.... the libarchive package in Arch Linux is not built against lrzip.

@Allan - I inspected the output of `./configure --help` from libarchive and didn't see anything relating to lrzip. Does that mean that what I'm asking for isn't possible? I.e. pacman being able to process foo.tar.lrz without the lrzip package?

That would require libarchive being built against lrzip and lrzip moved to [core]. Open a feature request - whoever maintains that will look into it.
