It's not that. 'last reboot' seems to be broken at the moment, at least
on stable/9:

I rebooted a few days ago:
lucid-nonsense:~:% uptime

And the utx.log file was last rotated over a week ago:

but last(1) isn't coming up with the goods:
lucid-nonsense:~:% last reboot
wtmp begins Fri Jun 1 06:14:46 BST 2012
(nor does it work if I tell last to use the older utx.log files)
Having investigated, the problem appears to be that wtmp used to use the
literal string 'reboot' in the username field of its records, while in
struct utmpx, that field is left blank but the record type field
indicates if this is the time the system shutdown or rebooted.
The attached patch fixes the problem for me. Or see
http://www.freebsd.org/cgi/query-pr.cgi?pr=168844
lucid-nonsense:~:% /usr/obj/usr/src/usr.bin/last/last reboot
boot time Mon Jun 4 22:58
shutdown time Mon Jun 4 22:54
boot time Sun Jun 3 09:43
shutdown time Sun Jun 3 09:39
wtmp begins Fri Jun 1 06:14:46 BST 2012
In passing, apparently it seems that creating a user with a username of
'reboot' is probably not recommended.
Cheers,
Matthew

Good point, I didn't take into account the command goes about a month back. I run FBSD in a vbox, and its only console anyways. I run Debian by default but in any event, there are many reasons for reboots and for me (typically) I see about 4 reboots a month mostly due to patching and sec-fixes. So indeed, YMMV is correct.
