freebsd-update and locally modfied files

[Zbigniew Szalbot]

Hello,

Can you help me by suggesting what I need to do when I want to use
freebsd-update fetch (FBSD 6.2) but get the following message:

The following files are affected by updates, but no changes have
been downloaded because the files have been modified locally:
/etc/rc.d/jail

Now, I do not recall ever playing with jail. Anyway, how do I update the
system (and keep changes to /etc/rc.d/jail (if any))?

Thank you in advance!
