Description:

My rc.conf file has "America/Sao Paulo" configured as time zone.
Since it has a space in its name, I think references to the time zone should enclose it in quotes.

Recently, 'rc.sysinit' was changed so that "/usr/share/zoneinfo/$TIMEZONE" is now properly enclosed in quotes.

However, there still is an unquoted reference to the timezone, as we can see below:

if [ "$TIMEZONE" != "" -a -e "/usr/share/zoneinfo/$TIMEZONE" ]; then
/bin/rm -f /etc/localtime
/bin/cp /usr/share/zoneinfo/$TIMEZONE /etc/localtime
fi

I think it should read like this:
/bin/cp "/usr/share/zoneinfo/$TIMEZONE" /etc/localtime

I have attached a patch for this change.

Steps to reproduce:
In rc.conf, configure a time zone that has a space in its name, then restart your system. Something wrong should happen.
