[Sugar-devel] Documents and Journal paths on sugar-build

[Samuel Greenfeld]

The one problem with extended attributes is that almost everything touching
and/or archiving the files needs to be aware of them.  Some utilities may
lack this functionality, and others have to be told to actively back these
up.

By means of example, XO laptops have to work around the fact that the ping
command in Fedora gets the permissions it needs via extended attributes for
the past several years.  The XO imaging solution is not extended attribute
aware, and at the time it was developed ping was still commonly set setuid
root.
