[uml-user] Why it doesn't work on Ubuntu 14.04?

[Balaco B. <bal...@im...>]

I'm remotely accessing an Ubuntu 14.04.2 machine. And now I'm trying to
run an UML in it, but it is always giving me some errors, and it
finishes with segfaults or coredumps.

For example, the end of output is:

=========================
request_module: runaway loop modprobe binfmt-464c
Starting init: /sbin/init exists but couldn't execute it (error -8)
Starting init: /etc/init exists but couldn't execute it (error -13)
request_module: runaway loop modprobe binfmt-464c
Starting init: /bin/sh exists but couldn't execute it (error -8)
Kernel panic - not syncing: No working init found.  Try passing init=
option to kernel. See Linux Documentation/init.txt for guidance.

=========================

I get the same error with the 32bit kernel, the 64 bit kernel and with a
kernel I compiled from source. The "init=" option didn't help either. I
don't know what else I should do.
