[elbe-devel] [PATCH] filesystem: add debug mode Parameter to TmpdirFilesystem

[Manuel Traut]

From: Torben Hohn <torben.hohn at linutronix.de>

> 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.
