How does one update SL 7 using a mounted USB flash drive as the source 
of a repo, rather than using any external network?  There were 
instructions for doing this for EL pre-7 distributions, but I cannot 
find similar instructions for SL 7.  I have a USB flash drive with the 
current double-layer DVD SL7.5 install image (ISO) and that does work -- 
I just did a fresh install of SL7.5 using this media.

If anyone needs to post a URL, please send me email at [log in to unmask] 
until I can change my registered SL list email address.  My university 
(not "mine" anymore, as Faculty here have little meaningful shared 
governance on these sorts of matters at this time) inspects all network 
traffic and rewrites all URLs to point to the campus URL security 
server/service (similar to the great firewall of the PRC), making access 
difficult or impossible.  This includes any bibliographic citation with 
a URL thus making bibliographic references impossible.
