1. Revamp package installer to use new dependency lists and also
pkg_add's new `read from stdin' mode to prevent a copy of the package
from hitting the disk unnecessarily.
2. More fixes for running "not as init" - don't get upset if CDROM already
mounted, do the right thing instead.
3. If running as init, assume first-time install and _don't show the
(W)rite option in the fdisk screen.
4. Many other little tweaks, some of which will have to wait for fuller testing
until I can create a boot floppy (testing certain system-destroying
features of sysinstall can be a royal pain). Expect some more commits.
don't bogusly restore the screen to the message that was the cause of the
abort. That resulted in lots of weird flickering dialog boxes that appeared
to be displayed out of sequence.
that the FTP install doesn't deal with timeouts and hasn't since it was
written. Fixed.
2. Totally eliminate the OptionFlags. I only had to work harder to
sync them with configuration variables, so why not simply always use
configuration variables? This has actually greatly simplified areas
of the code.
Remove the ATAPI kernel hack.
Remove the now-unnecessary work-around for booting root off a slice; it
appears to work just fine now and will confuse a lot fewer folks.
