The option is called B<--no-scripts> for historical +reasons as B<dh_installinitramfs> would previously generate maintainer +scripts that called B<update-initramfs -u>. + +Use this option, if you need to interface with the B<update-initramfs> +system that is not satisfied by the noawait trigger (e.g. because you need +the extra guarantees and head-aches of a await trigger). + +=back + +=head1 NOTES + +Note that this command is not idempotent.
