Hi,

I’m trying to encrypt the root filesystem / of a raspberry pi 4 device running under Devuan rpi ( custom kernel )

I’m following LUKS on Raspberry Pi 2021 guide

That explain step by step how achieve this.

But the guide use initramfs and my distro seem to use initrd

So the question, is: should I migrate to initramfs ? and how check whats is inside my current initrd

or keep-up with initrd but then how insert the necessary to enable LUKS drive to be mounted by it ( initrd ) ?

Thanks.

        Also systemd says I am using initrd (on my Fedora machine)

        systemd[1]: Running in initrd.

        But I have initramfs packed with dracut in /boot folder

        /boot/initramfs-6.12.8-200.fc41.x86_64.img

          Initramfs and initrd are 2 different things, the problem where the confusion happens is that initrd is deprecated since a few years.

          Now, systemd has implemented an interface called systemd-initrd which basically is initramfs.

          I guess here is were the confusion lies. Nowadays everything is initramfs even if it called initrd.

          The original initrd differs from initramfs, but it is no longer a thing.

          Sorry if i came across a little bit snappy have not had a great week so far.

        Based on first result

        We can use initrd for Linux kernels 2.4 and lower. Conversely, initramfs is for kernels 2.6 and above.

        Since on all modern system initial filesystem is tmpfs sometimes it is confused and initramfs is called initrd (for example: in grub to load initramfs you use initrd command).
