Package: schroot
Version: 1.6.10-1+b1
Severity: wishlist
Tags: patch
Hi,
schroot currently supports the gzip and bzip2 compressions for file-based
chroots. It might be worth to support alternative compressions to let
the user do a compromise between speed and space, depending for example
if the chroot is used often or not.
The patch below adds support for xz, lzop and lz4 compression, which
should cover most of the standard compression format available today.
Could you please apply it in one of the next uploads? Thanks.
Thanks,
Aurelien
