When using (for ex) grub-mkconfig, i got a bunch of warnings like: fgrep: warning: fgrep is obsolescent; using /bin/grep -F Using this command: equery files grub | xargs grep fgrep -l , i can only find two files installed by grub, that uses fgrep: /etc/grub.d/10_linux /etc/grub.d/20_linux_xen Reproducible: Always
Quoting from grep-3.8 release notes, https://lists.gnu.org/archive/html/info-gnu/2022-09/msg00001.html: "The egrep and fgrep commands, which have been deprecated since release 2.5.3 (2007), now warn that they are obsolescent and should be replaced by grep -E and grep -F."
This has been fixed upstream. I do not plan to backport the fix.
