Rationale: cpio -t alone cannot extract initrd past early cpio (microcode) in most packed initrd. unpack_initramfs.sh already under master comes to the rescue, but its usage up to today was limited to pass firmware blobs to final OS under boards/librem_mini_v2 Debian OSes (and probably others) need to have cryptroot/crypttab overriden directly, otherwise generic generation of crypttab is not enough. Extracting crypttab and overriding directly what is desired by final OS and exposed into /boot/initrd is the way to go otherwise hacking on top of hacks. This brings default packed modules under Heads to 5 modules, which needs to be deactivate in board configs if undesired: user@heads-tests-deb12:~/heads$ grep -Rn "?= y" modules/ | grep -v MUSL modules/zlib:1:CONFIG_ZLIB ?= y modules/zstd:3:CONFIG_ZSTD ?= y modules/exfatprogs:2:CONFIG_EXFATPROGS ?= y modules/busybox:2:CONFIG_BUSYBOX ?= y modules/e2fsprogs:2:CONFIG_E2FSPROGS ?= y
