From 82c0f34c7e62366c415470a3fe1a6a0c46e3d946 Mon Sep 17 00:00:00 2001 From: Ludovic Courtès Date: Sun, 2 May 2021 23:16:48 +0200 Subject: maint: Do not xz-compress ISO images. The xz-compressed image is 23% smaller than the original ISO image (with built-in zlib compression), but the extra decompression step is unconventional and often a hindrance for users. See discussion at . * Makefile.am (release): Do not compress ISO images. * doc/guix.texi (USB Stick and DVD Installation): Remove ".xz" suffix from URL and file name. (Copying to a USB Stick, Burning on a DVD): Remove introductory words, @enumerate, and first item.
