From 6ba8ecf9aa4e0ebf400b6e3e00e580569a623e58 Mon Sep 17 00:00:00 2001 From: Daniel Jordan Date: Wed, 4 Sep 2024 13:55:30 -0400 Subject: ktest.pl: Avoid false positives with grub2 skip regex [ Upstream commit 2351e8c65404aabc433300b6bf90c7a37e8bbc4d ] Some distros have grub2 config files with the lines if [ x"${feature_menuentry_id}" = xy ]; then menuentry_id_option="--id" else menuentry_id_option="" fi which match the skip regex defined for grub2 in get_grub_index(): $skip = '^\s*menuentry'; These false positives cause the grub number to be higher than it should be, and the wrong kernel can end up booting. Grub documents the menuentry command with whitespace between it and the title, so make the skip regex reflect this.
