Currently defined capabilities:
+ + revert
+ The "revert" command is supported. The base semantics
+ are that the following aspects of the testbed are reverted:
+ - the set of installed packages
+ - the contents of the root filesystem, BUT
+ - NOT the contents of /home
+ - NOT the contents of /tmp
+ - NOT the set of running processes
+
+ + revert-full-system
+ The "revert" and "close" commands will completely revert the
+ testbed to the state after "open". This reversion is done
+ with some kind of virtualisation, and includes (without
+ limitation) the contents of all the testbed filesystems, its
+ running processes, network configuration, etc. etc. etc.
+
+ revert
The testbed will actually revert when it is closed. If this
feature is not mentioned then changes to the testbed are
copydown of an executable file, `chmod +x' is run on the
destination file after the copy.
+ Both filenames are url-encoded.
