Package: initramfs-tools

X-Debbugs-Cc: gagath@debian.org

Dear Maintainer,

When updating initramfs with `update-initramfs -u`, the following output
appears on the console:

update-initramfs: Generating /boot/initrd.img-6.6.11-amd64

My guess is that update-initramfs is using cp with the -n option, and
that the --update=none option should be used instead, according
to the warning above.

Thanks in advance.
