I think that's *HIGHLY* dependent on the distribution.  Some systems
make it harder than others to get into single user mode.  I feel like
"sulogin" comes into play here.

The thing that I used to do is append "init=/bin/sh" to the GRUB boot
line via the transient editor.  Drops you at a shell and bypasses almost
all of the startup scripts.  Obviously there are ways to secure against
this.  But, again, it depends on the distro.
