kernel, rc.local, and xdm-config are typically softlinks. Plus other
files, of course, depending on how you setup your system.
rc.local and xdm-config might be softlinks into HT.DISKLESS, allowing
you to ease system administration when managing many diskless
workstations. You can also play other tricks, such as I play in
rc.conf.local by having it source ../HT.DISKLESS/rc.conf.local to get
class-based defaults.
Note: the ttys file below contains an example of how to have X startup
on boot.
