>Description:
	As dmesg prints out the system message buffer, which seems to be cyclic on
a byte boundary, the first line of dmesg.today / yesterday are some times fragments
of a line. Thus the diff done by check_diff in the periodic security report shows
undesired unmatched fragments.

>How-To-Repeat:
        Trivial.
>Fix:
        My suggestion is to add a "tail +2" in 700.kernelmsg (version 1.1.2.7),
to suppress first dmesg output line:

	cvs-freebsd:/etc/periodic/security>diff 700.kernelmsg 700.kernelmsg-
	47c47
	<       dmesg 2>/dev/null | tail +2 |
	---
	>       dmesg 2>/dev/null |

Gustavo
