>Environment:

	Standard installation

>Description:

	/stand/sysinstall is designed to be run either during system
	installation or after booting.  If it is started after
	booting, it will modify /etc/rc.conf, even if it doesn't need
	to.  It appears that it removes \r characters, thus making the
	file unusable.  After repeating, the file may be overwritten.
	Here is an example after 5 iterations of starting
	/stand/sysinstall and exiting immediately:

##############################################################

swapfile="NO"           # Set to name of swapfile if aux swapfile desired."             # Set to name of swapfile if aux
 swapfile desired."             # Set to name of swapfile if aux swapfile desired."             # Set to name of swapfil
e if aux swapfile desired."             # Set to name of swapfile if"           # Set to name of swapfile if aux swapfil
e desired."             # Set to name of swapfile if aux swapfile desired."             # Set to name of swapfile if aux
 swapfile desired."             # Set to name of swapfile if aux swapfile desired."             # Set to name of swapfil
e if aux swapfile desired."             # Set to name of swapfile if aux swapfile desired."     

>How-To-Repeat:

	Run /stand/sysinstall.  Exit immediately.

>Fix:
	
	Don't have time to look for one, sorry.
