From 7211773a55fe6e881cde15764a765f82b80ac588 Mon Sep 17 00:00:00 2001 From: Lennart Poettering Date: Thu, 1 Apr 2021 17:58:54 +0200 Subject: mkosi: work-around to make systemd build in Fedora images that lack populated /etc On Fedora /usr/bin/ld is a symlink managed via the "alternatives" system. This unfortunately means the binary is not usable in environments where /var or /etc are unpopulated. Let's address this by redirecting "ld" to "ld.bfd" manually if such an environment is detected, via $PATH. This is useful for building systemd in mkosi with UsrOnly=1 set. --- mkosi.build | 12 ++++++++++++ 1 file changed, 12 insertions(+) (limited to 'mkosi.build') diff --git a/mkosi.build b/mkosi.build index a74fc196be..ff339b440c 100755 --- a/mkosi.build +++ b/mkosi.build @@ -14,6 +14,18 @@ if ! mountpoint -q "$SRCDIR"; then umask 022 fi +# On Fedora "ld" is (unfortunately — if you ask me) managed via +# "alternatives".
