Directory Description:

The content of /usr/testbed directory:

boss# ls
backup          expinfo         libexec         opsdir          www
batch           expwork         lists           sbin
bin             images          locks           tftpboot
etc             lib             log             usersvar

og	store all logs , such as apache access, tmcd
libexec	all executable perl scripts & programs ( compiled from C codes), not directly used.
bin	some program directly related to testebed and images.
sbin	programs like ipod, proxydhcp, frisbeed, rmuser,....etc
www	web service scripts
lib	.pm files , Perl 5 Libraries. libdb and libtestbed are most important.
etc
opsdir

After boss-install, most other directories are empty.

Observe the /usr/testbed directory in OPS, after ops-install. only five sub-directories:

ops# ls
bin     etc     lib     libexec sbin

Source Directory: No matter where the snapshot was put, the utmost directory is testbed/. I put the snapshot in the ~zhibinwu/orbit_source/ of Boss server
Object Directory: root/tbobj directory in Boss server. The object directory is just used to compile binaries and store temporary copes of some stuff that gets run through the configure script. It's the /usr/testbed directory that everything actually runs from - it's safe to remove your object directory after installing (though there is usually no need to do so).
Running Directory: It's the /usr/testbed directory of Boss server that everything actually runs from.
