[elbe-devel] [PATCH v1 4/8] Check existance of '/rfs/etc/apt/preferences' with 'lexist'

[dion at linutronix.de]

From: Olivier Dion <dion at linutronix.de>

Since we're going to write to '/rfs/etc/apt/preferences', we
want to make sure that we don't write to a broken link.

Also, change from using 'os.path' methods to 'self.rfs'
methods to be more consistent.
