Yeah, I tried to create the symlink on Solaris using the tc-terminal-server script. It created the link, but PXE still didn't work. I had to give up on TC and installed Debian with the ISC DHCP server. The minimal Debian installation I made is less than 600MB, but that's still way more than it would take for TC to do the same work. I'll create a ISC DHCP extension when I get a chance.
