    Disable FIPS mode

    What does this command 2nd line do? It seems it removes the fips=1 argument from the kernel command line. Should this command be a one-liner? I was not able to run each line separately. grubby --update-kernel=ALL --remove-args=fips=1 [[ -f /etc/default/grub ]] && sed -i 's/ fips=1//'...
