install initramfs hooks and setup maintscripts


dh_installinitramfs [debhelper options] [-n]


dh_installinitramfs is a debhelper program that is responsible for installing Debian package provided initramfs hooks.

If dh_installinitramfs installs or detects one or more initramfs hooks in the package, then it also automatically generates the noawait trigger update-initframfs command needed to interface with the Debian initramfs system.  This trigger is inserted into the packaging by dh_installdeb(1).



Assumed to be an initramfs hook that will be installed into usr/share/initramfs-tools/hooks/package in the package build directory. See HOOK SCRIPTS in initramfs-tools(8) for more information about initramfs hooks.


-n,  --no-scripts

Do not add the update-initramfs trigger even if it seems like the package might need it.  The option is called --no-scripts for historical reasons as dh_installinitramfs would previously generate maintainer scripts that called update-initramfs -u.

Use this option, if you need to interface with the 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).


Note that this command is not idempotent. dh_prep(1) should be called between invocations of this command. Otherwise, it may cause multiple instances of the same text to be added to triggers file.
