I want to review that the hooks used to build the initrd.img are correct in my debian but I fail to find the /etc/mkinitcpio.conf file like the one in Archlinux, what is the equivalent of this file in debian and how do I rebuild the initrd.img once I've edited that file ?

To configure the initramfs in Debian, you can modify /etc/initramfs/initramfs.conf, or add configuration files and hooks to /etc/initramfs/conf.d and /etc/initramfs/conf-hooks.d.

To rebuild the initramfs, run update-initramfs as root with the appropriate options (update-initramfs -u to update the initramfs of the newest kernel).

All this is in the initramfs-tools and there are manpages documenting the various commands and configuration files.
