Hello!
I have an UltraSPARC machine with Solaris 8 installed, but I want to switch
it to NetBSD. As I'm not familiar with this architecture, I have a few
questions:

1. Is NetBSD/sparc64 stable enough to use it on quite important machine?
2. How does it's performance look like, in comparision with Solaris?
3. Can I have more than one virtual terminal? I've read in maillist archive
that X will not run on this.

Thanks in advance!

My machine identifies as:

# uname -a
SunOS system 5.8 Generic_108528-15 sun4u sparc SUNW,Ultra-5_10
