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.

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).

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
