upgrading

this is sample about DHCP-agent

Notes on upgrading
------------------

Generally speaking "upgrading" at this point in the suite's
development stage isn't recommended. Get rid of the old
installation with make uninstall and reinstall from the new one.

From dhcp-agent-0.37
--------------------

A lot has changed. Actually enough that you should probably do the following:

If you already have a source tarball of the distribution you can
configure it with the same prefix (or the default one) and do a
make uninstall. You will also need to delete /etc/dhcpclient

If you don't have a source tarball but installed everything in
/usr/local you can do the following:

rm -f /usr/local/bin/dhcpclient /usr/local/bin/dhcpsniff
rm -f /usr/local/man/man1/dhcpclient.1 /usr/local/man/man1/dhcpsniff.1

Also delete the /etc/dhcpclient directory since it is no longer used.

New binaries have a hypen in between dhcp and their name. So:

dhcpclient is dhcp-client
dhcpsniff is dhcp-sniff

The same applies to the man pages.

From dhcp-agent-0.36
--------------

dhcpclient:

The new parser requires strings with spaces to be wrapped in
quotes. You can either hand edit the files in /etc/dhcpclient (or
where the work directory is defined), and add these quotes or
delete the files so they are regenerated. This affects the cache
too.
