Please don't. Someone on IRC told me Xen also has some framebuffer
feature. Say, someone would port syscons to Xen, the naming would
conflict with the console device node. /dev/xc0 is good enough. I even
think it should have been called ttyx0, not xc0.
Given that there will be increasing levels of support for "pass-through"
hardware access in virtual machine environments and a trend in the
direction of virtualization-friendly hardware, we shouldn't preclude the
possibility of something a lot closer to syscons working inside of Xen
in the future. This means we should leave the syscons device names open
so that syscons can claim them if desired.
HVM mode already supports "pass-through" with syscons working in it.
That is orthogonal to the discussion of supporting the native
virtualization features of Xen.
