I've been working on an operating system using the Linux kernel. I've successfully compiled the kernel and can boot into my initramfs through it.

The issue arises when I try to switch from initramfs to the actual boot device the operating system has been booted from. For this, I've even set up a system to programatically determine the boot device so users can boot the OS from a bootable USB or even a CD with the OS burnt onto it.

Everything works well until I try to use switch_root: it fails and afterwards, my OS becomes unable to run some stuff saying pty cannot be found. Please help.

  • Please provide the failure message and the exact pty failure message. Also, do you have an fstab file written?

Fortunately, I've come to a solution.

I switched from creating my own initramfs with BusyBox and instead have an automatic one created using dracut. dracut handles the mounting of the root file system and even the switch to it.
