unable to use crosssystem

[pazza2234]

Describe the bug

(original issue)

I can not run depth boot because I cant do this, and it is on there (tutorial)[https://eupnea-linux.github.io/docs/depthboot/build-instructions]. Think it is a murk mod or fake murk problem because of warning: /mnt/stateful_partition/mwtrollinggoogleforfakemurk: warning: script from noexec mount and in the murk mod setup it tells us to not make issues on fake murk if we have murk mod.

I have a problem, where I can not run this command sudo crossystem dev_boot_usb=1 dev_boot_signed_only=0 with out it either giving the error /usr/bin/crossystem: line 170: warning: /mnt/stateful_partition/mwtrollinggoogleforfakemurk: warning: script from noexec mount; see https://chromium.googlesource.com/chromiumos/docs/+/master/security/noexec_shell_scripts.md or, after I remounted /mnt/stateful_partition with exec, and executed it it looked fine but gave me a error when I pressed ctrl + u that I have not enabled USB boot.

To Reproduce

1. go to Chromebook, open shell and type sudo crossystem dev_boot_usb=1 dev_boot_signed_only=0
2. have it fail, and run mount -o remount,exec /mnt/stateful_partition
3. run step 4 again
4. reboot to the Dev mode screen where you normally press ctrl + d
5. it gives you a error code in the top left of the screen wile the image stays there... and the error code warning: booting from external media (USB/SD) has not bin enabled

Additional context

• My Chromebook is the dell 3100, and is on the octopus board.
• I am stupid so I might ask a few dumb questions sorry.
• It is on chrome OS 107.
• Root verification is off.
• I might enable it if it is a solution, but I do not got legacy bios enabled.
• I am not using ctrl + c and ctrl + v to type this, so it may not be 100% accurate but I typed as well as I could. It all looks right. Sorry if I missed type something.

this was originally a issue I made on depthboot-builder but they told me to come here.

here is a copy of cross-system thingy. is it broken or something? crossystem(copy).txt (also, this is what normally happens with out remounting /mnt/stateful_part)

localhost ~ # crossystem dev_usb_boot=1
/usr/bin/crossystem: line 170: warning: /mnt/stateful_partition/mwtrollinggoogleforfakemurk: warning: script from noexec mount; see https://chromium.googlesource.com/chromiumos/docs/+/master/security/noexec_shell_scripts.md

I have some instructions on this exact topic here, with modified instructions for fakemurked devices. If that doesn't fix your problem, re-open this issue.

Also, real-time modification of crossystem values aren't possible. If you want to set a value in crossystem, you'll have to manually run vi $(which crossystem) to edit in the values yourself.
