Talk to the upstream tar maintainers about ways to make tar detect if
lbzip2 is available and use it instead of bzip2.


As the maintainer of the Debian packaging of tar, I'm ok with Sergey's
proposal in [0].

Sergey, Bdale, as its timestamp shows, my most recent post in the matter is [1]. If you still feel this modification of tar is worth it, I'll gladly do my part if there will be any (eg. installing the lbzip2 alternative for /usr/bin/bzip2-filter or so).

AnĂ­bal, I believe it would be useful if pbzip2 installed a bzip2-filter alternative as well. pbzip2 cooperates with --use since v1.0.4.

So how about working (Sergey, I don't mean you) on making lbzip an actual replacement for bzip? I know that isn't being done now, but that doesn't it couldn't be done. Free software and all that.

I've been thinking about making lbzip2's command line and compressed output more similar to those of bzip2. Even if I get anything done on this front, I can only promise *not* to support -f/--force, and (if implemented at all) make -k/--keep the default. lbzip2 will neither remove nor overwrite files, regardless of the NO WARRANTY clause of the GPL.

Furthermore, I'm reluctant to introduce long options at all.

Paul, if these would block acceptance of lbzip2 as a bzip2 alternative, please tell me up-front so I don't need to bother hacking upstream.

Karl, my apologies.
