[PATCH 00/21] Improve VT Handling

[Scott James Remnant]

One of the main differences between Ubuntu's use of Plymouth and
Fedora's is that on Ubuntu we've tried to keep the X server on VT7
so that the historical documentation of Ctrl-Alt-F1 giving you a
text console is preserved.

This obviously means that for a smooth transition, Plymouth must also
run on VT7.

We discovered that although Plymouth does have code to attempt to deal
with VTs, none of it is quite right and there are many paths that don't
work unless Plymouth is run on VT1.

This patch set fixes our known problems with the VT handling making it
possible to run Plymouth on any VT of your choosing, with VT1 remaining
the default.
