Hi,
I'm a dino since I still use grub-1 but I prefer recent kernels
(currently 4.70-rc4)
I don't understand the 'root=' option on the boot line like
kernel /boot/vmlinuz-4.7.0-rc4 root=/dev/sda1
Here my bad experience:
Having booted by SystemRescueCD from the cdrom device, my root device
is labelled /dev/sda1
BUT trying to use that on the kernel boot line fails (the kernel
cannot find the root file system)
By trial and error I've found that I have to use root=/dev/sdb1
but if I plug in an external drive (via USB) this doesn't work any more.
So, I came up with root=UUID=uuid_number of the root file system.
But to my surprise I now got a kernel panic
syncing: VFS: unable to mount root fs on unknown block(0,0)
So, please tell me what I'm missing?
Many thanks!!!
Helmut
