>Description:
rc.diskless1 creates an mfs /etc which is sized to 4096 sectors [~1.9M]. Since XFree86-4.1 puts many of its files now in /etc/X11 [with symbolic links from /usr/X11R6/lib/X11 (where they used to be located)], the original size allocated for the mfs /etc is too small. When trying to boot a diskless workstation with XFree86-4.1 on the system, the boot will fail because there is insufficient space in the mfs /etc.
>How-To-Repeat:
Configure a diskless workstation server with FreeBSD-4.5-Release and XFree86-4.1. Create a root hierarchy for the diskless root mount point with clone_root and boot a diskless workstation from this server [using the bootp/DHCP method as outlined in the handbook].
>Fix:
Edit rc.diskless1 [v 1.5.2.6 2001/05/11] as outlined below. This creates a bigger [maybe a little too big?] mfs /etc, so that populating it doesn't result in diskless boot failure. NB: this rc.diskless1 file should be edited in /etc *before* clone_root is run. If fixing this after clone_root has been run, then it must be edited in /<diskless root mount point>/etc.
