5# NOTE about permissions in OpenZaurus
6 # The devices in question here by default
7 #are accessible to everyone in the group in
8 #question. We wish to ensure that, as a policy
9 #choice, a login to opie makes access to these
10 #devices exclusive by 1) changing device ownership
11 #to the user, and 2) removing group access.
12#
13 #A better implementation would probably be to store
14 #existing device permissions at load time, and restore
15 #them at exit, rather than making assumptions about
16 #user/group ownership, or permissions.
