>Description:
The command:

	ezjail_admin update -b

responds with an error message on my system:

	Error: Cannot find your copy of the FreeBSD source tree in .
  	  Consider using 'ezjail-admin install' to create the base jail from
          an ftp server.

Opposite to the message, the FreeBSD source tree is installed under /usr/src
and the respective path is set in /usr/local/etc/ezjail.conf (ezjail_sourcetree).

Another system with ezJail 3.1 works fine with the same settings. I drilled
down the problem with diff of ezjail_admin version 3.1 vs. 3.2.2. It looks
like that 3.2.2 within the  #### ezjail-admin UPDATE ##### section unsets a
couple of variables but never assigns them again. Thats why later in the code: 

	# Bump the user for some of the most common errors
    [ -d "${ezjail_sourcetree}" ] || exerr "Error: Cannot find your
    copy of the FreeBSD source tree in ${ezjail_sourcetree}.\n  
    Consider using '${ezjail_admin} install' to create the base 
    jail from an ftp server."

exits with the error.

The problem was already reported to ezjail@erdgeist.org (the ezJail
mailing list). This PR is for informational purpose.
>How-To-Repeat:
After the installation of ezjail, try to update the basejail with:

ezjail_admin update -b
>Fix:
I could fix the problem in 3.2.2 temporarely by changing the line:
	unset ezjail_provideports ezjail_installaction ezjail_osversion_source
	ezjail_osversion_destination ezjail_sourcetree
to:
	unset ezjail_provideports ezjail_installaction ezjail_osversion_source 
	ezjail_osversion_destination
