Any reason you add this command before set -e ?
It seems we want the script to fail if module can't be loaded.
Cause if CONFIG_NF_DEFRAG_IPV6=y, the script would unnecessarily fail.

I don't think modprobe fails when code is built in.
$ sudo modprobe pstore $ echo $? 0 $ grep CONFIG_PSTORE= /boot/config-5.7.8-200.fc32.x86_64 CONFIG_PSTORE=y $ lsmod | grep pstore $
