[elbe-devel] [PATCH v2 1/6] filesystem: add debug mode Parameter to TmpdirFilesystem

[Torben Hohn]

debugging things, that happen in TmpdirFilesystem, is not really
possible.

Add a debug parameter to TmpdirFilesystem.__init__() that makes
it leave the directory undeleted, and also makes it print out
the path to the directory.
