>Description:
When boot server exports its own root as a rootpath to the client,
the latter falls back to /pxeroot
	
>How-To-Repeat:
1. Enable tftpd
2. Copy /boot/pxeboot to the tftpd root (/tftpboot/)
3. Add lines
  filename "pxeboot";
  option root-path "/";
to the dhcpd.conf
4. Restart dhcpd
5. Try to boot some machine over the network
	
>Fix:
Workaround:
  option root-path "//";
