From a091409f105f4944e81449123b229d7b4cc4844a Mon Sep 17 00:00:00 2001 From: Coiby Xu Date: Oct 27 2022 06:47:57 +0000 Subject: use /run/ostree-booted to tell if scriptlet is running on OSTree system Related: bz2048690 Upstream: Fedora Conflict: None commit f6bcd819fc2645f762946a802c15684e7627f379 Author: Coiby Xu Date: Fri Jul 15 15:11:44 2022 +0800 use /run/ostree-booted to tell if scriptlet is running on OSTree system Resolves: bz2092012 According to the ostree team [1], the existence of /run/ostree-booted > is the most stable way to signal/check that a system has been > booted in ostree-style. It is also used by rpm-ostree at > compose/install time in the sandboxed environment where scriptlets run, > in order to signal that the package is being installed/composed into > an ostree commit (i.e. not directly on a live system). See > https://github.com/coreos/rpm-ostree/blob/8ddf5f40d9cbbd9d3668cc75b703316e0a89ab11/src/libpriv/rpmostree-scripts.cxx#L350-L353 > for reference. By checking the existence of /run/ostree-booted, we could skip trying to update kernel cmdline during OSTree compose time.
