From 924a97aeb1a5ed03529aa766f579a145ae67261a Mon Sep 17 00:00:00 2001 From: nl6720 Date: Thu, 11 Apr 2024 16:13:30 +0300 Subject: configs/releng/profiledef.sh: use zstd compression for bootstrap image The zstd tool has now been around for a while, so the availability of it should not be a concern anymore. Unlike gzip which was used until now, zstd offers higher compression while still being faster (and multi-threaded). The `--auto-threads=logical` option is used just so that there is some difference between the releng and baseline profiles. Everyone using the official Arch Linux bootstrap tarball (previously `archlinux-bootstrap-YYYY.MM.DD-x86_64.tar.gz` or `archlinux-bootstrap-x86_64.tar.gz`) will need to update their scripts and etc. to use `archlinux-bootstrap-YYYY.MM.DD-x86_64.tar.zst` or `archlinux-bootstrap-x86_64.tar.zst` instead.
