As long as guests are unprivileged users that cannot change things outside of their home directory (/home/guest ?) this is relatively simple.

You can make a copy/backup of the freshly created guest user's home directory:

Code:

cp -rp /home/guest /home/guest_bak

and on startup remove the guest home directory and copy the backup back into place.

If you made a backup as "/home/guest_bak" (directory not file). Then you can make a script like:

Code:

#!/bin/sh

rm -f /home/guest
cp -rp /home/guest_bak /home/guest

Give that script a name like clean_guest.sh, move it to somewhere like /usr/local/bin, make it executable:

Code:

chmod +x /usr/local/bin/clean_guest.sh

Call it from inside /etc/rc.local (redhat) or similar init script and now any changes made or files copied will be gone and have a freshly built user home again.

createhomedir

createhomedir(1)					    BSD General Commands Manual 					  createhomedir(1)

NAME

     createhomedir -- create and populate home directories on the local computer.

SYNOPSIS

     createhomedir [-scbalh] [-n directoryDomainName] [-u username]

DESCRIPTION

     createhomedir provides several options for creating and populating home directories.

OPTIONS

     -s       creates home directories for server home paths only (default).

     -c       creates home directories for local home paths only.

     -b       creates home directories for both server and local home paths.

     -a       creates home directories for users defined in all directory domains of the server's search path.

     -l       creates home directories for users defined in the local directory domain.

     -n directoryDomainName
	      creates home directories for users defined in a specific directory domain in the server's search path.

     -u username
	      creates a home directory for a specific user defined in the domain(s) identified in the -a, -l, or -n parameter. If you omit the -a,
	      -l, and -n parameters when you use the -u parameter, -a is assumed.

     -i       reads username list from standard input and creates specified home directories. Each username should be on its own line.

     -h       usage help.

FILES

     /usr/sbin/createhomedir			   location of tool

CAVEATS

     When using the -a option, search limits of various directory servers (such as Open Directory or Active Directory) can prevent all possible
     home directories from being created. In this case, you may need to specify the usernames explicitly.
