I noticed that the other day too.

Yesterday I did some debugging and finally decided that the most  
recent change to include the current proper URL was done blindly by  
some search-and-replace blast.

However even without the current URL being included the old logic  
fails miserably if the source directory (-s) is specified as the real  
source tree (as opposed to a directory where the *etc.tgz set(s) were  
unpacked).

The better fix would be to edit the old URL into the new one without  
grubbing about in any source directory for a new template file.

Furthermore the use of "mktemp" in the do_motd() function is also  
wrong.  Postinstall sets up its own private (and much safer to use)  
scratch directory which all such functions should use for temporary  
files.

Perhaps it could be something like the following (untested and  
probably badly folded):

do_motd()
{
        [ -n "$1" ] || err 3 "Usage: do_motd fix|check"

	if fgrep -i 'netbsd.org/Misc/send-pr.html' ${DEST_DIR}/etc/motd > / 
dev/null 2>&1; then
                result=1
                if [ "$1" = check ]; then
			msg "NetBSD.org bug reporting URL needs updating to replace /Misc/  
with /support/"
                else
			sed 's|/Misc/|/support/|' < ${DEST_DIR}/etc/motd > ${SCRATCHDIR}/ 
motd.newURL
                        mv ${SCRATCHDIR}/motd.newURL ${DEST_DIR}/etc/motd && 
result=0
                fi
        else
                result=0
        fi

        return ${result}
}
