Depends upon what issues. If you boot with init=/bin/bash, you have a
single user multitasking machine. "init" can be any program that you
want to write.

This means that you can make anything you want, simple to complex, with
the capability of doing all the "Unix" things. I use this technique for
our name-server. It is secure because all it does is serve names. One
can't execute a shell because there isn't any. In this case, "init" is
a simple program that execs stuff necessary to set up the network, then
it overwrites itself with named/bind.
