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.
Not sure I follow this comment: what I'm saying is that the Xen-specific
console device should not use the same device names as syscons, so that the
two can coexist in a single installation.
