Re: [PATCH 7/7] archive: provide builtin .tar.gz filter

Also, since it's easy via the external helper route, should there be any
other builtin formats? Bzip2? It's not that big a deal for a big hosting
site like kernel.org to stick it in their configuration, but I wonder if
normal users would find it useful.

I know k.org statically prepares *.bz2 for any *.gz in /pub/software/
hierarchy, but isn't bzip2 significantly more expensive (like taking ten
times as much memory or four times as much CPI time to squeeze the last
extra 15% out), making it unsuitable for one-shot online use?
