#StackBounty: #linux #kernel #boot #linux-kernel #kernel-parameters Linux Modify/Add Kernel Command Line from InitramFS "UserSpace…

Bounty: 100

I am developing an embedded Linux device. I have successfully created an InitramFS CPIO archive that runs quickly after boot. Now, I want to change the initial kernel command line to include “quiet” parameter so I can boot even faster.

However, once the splash screen is displayed in the InitramFS, I want to remove the quiet option for the kernel so the remainder of the boot is NOT quiet.

How can I achieve this? How can I reverse the initial “quiet” kernel command line option once I’ve reached the InitramFS?

Thanks.

So I was trying to mount a drive on boot. I was editing /etc/fstab and then I rebooted to see if my drive would mount on boot. Now I can’t do anything. The prompt I see
Give root password for maintenance
(or press Control-D to continue):

When I press Control-D this prints: sulogin: cannot read /dev/tty1: Operation not permitted

I’ve tried all kinds of root passwords but none of them work. I tried to tap shift while it boots and nothing happens.

EDIT: This question is not a duplicate because when I press Control-D at the prompt I get an error message

I’m on a Pine64. Is there any way to salvage the device or save the files?
