as forrest gump said, "it happens". the wtmp file can get
borked, and then reports based on it can get fuxnored.

after moving/clobbering the files you may need to restart your
logging facilities; they will most likely still be writing their
information to their open file handles, which would still point
to the old (marked-for-deletion-or-whatever) files.

	/etc/init.d/sysklogd restart|reload|yadayada <i think>

DEBIAN NEWBIE TIP #67 from Colin Watson <cjwatson@flatline.org.uk>
:
Did you know MANPAGES ARE IN SEVERAL SECTIONS?  For example,
user commands are in section 2 of the manual, and system
administration items are in section 8; to request a particular
section via "man" include it before the item:
	man 7 regex
(otherwise you'll probably see regex from section 3 instead.)
To see ALL pages with a particular name, try
	man -a regex
every matching manpage (from whichever section) will be
presented, one-by-one.
