What were you trying to do that didn't work?

Installing a 3rd party kernel module rpm generated a warning message:

grep: warning: stray \ before /

I tracked this down to dracut.  The file /usr/lib/dracut/modules.d/90kernel-modules-extra/module-setup.sh seems to be the cause.  I believe the re_escape() in that file is adding an unnecessary '\' in front of the / in path names.  The stricter grep in RHEL 10 then prints the warning.

What is the impact of this issue to you?

Seeing a warning message when installing a Cisco kernel module rpm is not desirable.

Please provide the package NVR for which the bug is seen:

dracut-105-4.el10_0.x86_64
