Please wrap you lines aroun 72 chars.  See

If you're shooting for max uptime and the most stable system, you can
follow the procedure I follow for most of my clients:
1) Install the latests 4.x-RELEASE
2) cvsup to RELENG_4_x (currently RELENG_4_10)
3) rebuild/reinstall the core system.
4) When 4.11 comes out, schedule a weekend and cvsup the system to
   RELENG_4_11, rebuild/reinstall.  Pay special attention to
   /usr/src/UPDATING, repeat for 4.12, etc
5) Subscribe to FreeBSD-security.  When a vuln is announced, recvsup
   to the RELENG_4_x and rebuild/reinstall
6) Step 5 can occasionally be skipped.  For example, there were many
   sites that I had using FreeBSD that I didn't have to update when
   bind problems were fixed, because they weren't running DNS servers.
   If you're not sure, you're safer updating than not.
