You can start uml in gdb e.g. like this:
gdb --args ./linux ubda=root.img
Then use the gdb same commands you would when you debug a user space program.
If you encounter segfauls during the boot of the uml, just ignore them and
type "cont". They are caught by a signal handler in the uml process and do not
cause any harm. But gdb will display them anyway.
