Hi, I am starting to study the linux kernel and I was wondering why did you choose to use the initrd design, instead of initramfs (kernel >= 2.6) for the initial ramdisk at the boot process. Is there any motive in special?

Hey, hope you are doing well. I was trying to build a buildroot to simply stream a USB camera on HDMI. I have one error that I'm stuck to. /dev/video0 no such file or directory. Either I use vlc to capture, gstreamer, ffmpeg everywhere. I'm making this on my windows using wsl. Can you help me with this? Please

Note: if you get kernel panic about not finding init, please create a symlink in your initrd root directory before creating it for the kernel:

ln -s /sbin/init init

This will link /init to /sbin/init and fix the error

Top! But is it possible to convert this from qemu to vmware?

[HomelessDeamon]

does it have working networking so that you can boot into it after u pack it as iso and start building inside it.

I have a problem. I cpio and gunzip the initrd and i boot with qemu. For some reason, it doesnt wanna work because it cant find an init or i get the error unable to mount VFS

Very good stuff!
I do have a problem when booting.
I get "Kernel panic - not syncing: No working init found."

How to fix?
