+=head1 SYNOPSIS
+
+B<dh_installinitramfs> [S<B<debhelper options>>] [B<-n>]
+
+=head1 DESCRIPTION
+
+B<dh_installinitramfs> is a debhelper program that is responsible for
+installing Debian package provided initramfs hooks.
+
+If B<dh_installinitramfs> installs or detects one or more initramfs
+hooks in the package, then it also automatically generates the noawait
+trigger B<update-initframfs> command needed to interface with the
+Debian initramfs system.  This trigger is inserted into the
+packaging by L<dh_installdeb(1)>.
+
+=head1 FILES
+
+=over 4
+
+=item debian/I<package>.initramfs-hook
+
+Assumed to be an initramfs hook that will be installed into F<<
+usr/share/initramfs-tools/hooks/I<package> >> in the package build
+directory. See B<HOOK SCRIPTS> in L<initramfs-tools(8)> for more
+information about initramfs hooks.

+
+=head1 OPTIONS
+
+=over 4
+
+=item B<-n>, B<--no-scripts>
+
+Do not add the B<update-initramfs> trigger even if it seems like the package
+might need it.  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. L<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.
