From d14d0c1aea8fe0eb61b7788a3b546475e183b079 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Tue, 14 Apr 2020 18:56:08 +0200 Subject: scripts: sphinx-pre-install: improve distro detection check The Arch-linux detection is hit by catting /etc/issue, whose contents is (nowadays): Arch Linux \r (\l) It sounds a little ackward to print such string, so, instead, let's use the /etc/os-release file, with exists on lots of distributions and should provide a more reliable result. We'll keep the old tests before it, in order to avoid possible regressions with the other distros, although the new way should probably work on all the currently supported distributions.
