Comment 1 for bug 228495

This is an issue because full UME builds with tar ball are quite large (in excess of 2 Gig) and because Moblin Image Creator requires root we can not create private builds in the data center (the IS department will not grant root access to anyone in the datacenter). Thus we have to create private builds on a machine local to a developer and then move the entire image up to the data center. Building in this fashion causes long delays (up to and including a day).

If M-I-C used fake root or one of the other standard methods of not really having to use real root access it would be possible to do a full private build much faster as it would avoid both the download time and the upload time, for a Beta from scratch this can amount to 6-10 hours.
