freebsd-src/sbin/sysinstall/termcap.c
Poul-Henning Kamp aa7d974a35 Fixed to make sysinstall work again. Notable changes:
Removed a dialog_clear() which somebody aimlessly had slammed into TellEm()
in absence of any understanding of the structure of this program. :-(

Skip through stage0 for now.

Make write_bootblocks write the disklabel using the kernel-call, and forget
about the boot-blocks for now.  This is wrong, but I havn't found the real
problem yet.  I will continue work on this problem.

Added a Debug-feature.  There is a printf' like Debug() now which sends its
output to ttyv1 (Alt-F2), and all "discarded output" from sub-processes end
up there too.  Made TellEm() put it's messages there also, so that we can
see where what happens.

Set the PATH for the shell we shouldn't start at the end :-)

set "npartitions" after the disklabel-editor returns, so that we actually
can edit all the 8 parts of the label.
