Potential BUG: update_motd="YES" is prepending same text on ever reboot

[Rahul Bharadwaj]

Ok after a bit more debugging I found the issue.

The kernel has a different uname output (i.e. "uname -v" does not return
"FreeBSD" in its output). So when /etc/motd is run , the following awk
command runs (inside of /etc/rc.d/motd):

awk '{if (NR == 1) {if ($1 == "FreeBSD") {next} else {print "\n"$0}} else
{print}}' < /etc/motd >> ${T}

In this, the check is done only for "FreeBSD" and thus for this
non-standard BSD kernel, we were seeing the same line being appended to the
file.
