>Organization:
Netasq
>Environment:
System: FreeBSD alexandreb.netasq.com 6.1-STABLE FreeBSD 6.1-STABLE #11: Fri Aug 11 14:04:23 CEST 2006 root@alexandreb.netasq.com:/usr/obj/usr/src/sys/GENERIC i386
>Description:
The boot loader won't display all the parameters present in /boot.config because the parse() function will alter the string before displaying it.
>How-To-Repeat:
Put more than one parameter in /boot.config
>Fix:
Duplicate the string before displaying it.
