Where did this go?

Do we have any additional opinions regarding LZMA? Personally, I think
LZMA is great, and the new licensing (LGPL?) opens a lot of doors.
Personally, I can't wait to see squashfs-lzma to pick up speed.

I agree with Dan though - libarchive isn't just a dep of pacman. We
also ship bsdtar, which I use quite often.
