[arch-dev-public] moving lz4 to [core]

[Dave Reisner]

Hi,

lz4 is growing in popularity as a compression algorithm. As of systemd
216, systemd-journald supports lz4 (in addition to xz). Benchmarks[1]
were provided at the time Zbigniew wrote the patches to show the
impressive drop in CPU required to compress journal files.

There's already a feature request to enable this[2], and a complaint
about the excessive CPU usage of XZ in the presence of a program which
doesn't behave[3] in some given environment.

So, with that, is anyone opposed to moving lz4 to [core] so that systemd
can sanely depend on it?

Cheers,
d
