From 7f7ca896e6cf5c61243d56ae3faaf8edb3872469 Mon Sep 17 00:00:00 2001

Subject: Various minor optimizations to speed up boot. (<arjan@infradead.org>)

Notable:
- separate [ "$variable" ] tests from [ -f ... ]
- don't grep init scripts
- cache the information from /sbin/consoletype
- simplify 'confirm' handling
