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.

Boot on LUKS drive ( Rapsberry pi 4 ) (self.linux)

submitted 2 weeks ago by SpongeB0B to c/[email protected]

7 comments fedilink hide all child comments

Hi,

The SBC Raspberry Pi 4 boot on an sdcard with two partition /boot and /

So I managed to encrypt the partition / with cryptsetup

Here the partition of my sd-card

device	FILESYS	LABEL	UUID
sdb1	vfat	BOOT	( 9 characters )
sdb2	crrypto_LUKS		( 36 characters )

I've modified the /boot/cmdline.txt

to ( on one line )

console=serial0,115200
console=tty1
root=UUID=#If I try the UUID of sdb2 it fail and also the UUID when I use `cryptsetup luksOpen /dev/sdb2 b2open`
rootfstype=ext4
fsck.repair=yes
loglevel=5
net.ifnames=0
firmware_class.path=/lib/firmware/updates/brcm
rootwait
cryptdevice=UUID=#I dont know which one:b2open

any ideas ?

Thanks.

I'm not sure I understood you correctly, is the problem just that you don't know which uuid-s to use where? Cryptdevice corresponds to your sdb2, and root is /dev/mapper/b2open. Otherwise, provide the exact error

I believe my initramfs do not support luks encryption, but the link of @[email protected] might work.... 🤞

Depends on the distro. On arch you need to enable a few hooks, for example
