New Revision: 228798
URL: http://svn.freebsd.org/changeset/base/228798
Log:
Add placeholder code for prepending pathnames to tftp.
At work we have a single tftp server that provides installation data for
a variety of operating systems. I'd rather place our FreeBSD-related
files in a subdirectory, instead of the root.
It would be nice if this setting could be run-time configurable, but at
least in our specific case, this is not possible, as pxeboot is
chainloaded through pxelinux.
