Main changes:
- Hotkey interactive startup has been removed, for a variety of reasons:
1) It doesn't work well with plymouth
2) interactive mode can never work right in a more strongly upstart or systemd
environment
For those that still need it, the interactive mode can still be accessed by
booting with 'confirm'.
- single-user mode now uses a helper program to execute bash, for use with
SELinux. This fixes the long standing issue of commands in single-user
mode being unable to write to the terminal.
Full log attached.
