Hi,

I noticed an interesting error while trying to roll a xo-1.75 build on
the xo-1.75 laptop.

While downloading, some of the rpm packages were html files (which is
a transient thing with fedora mirrors).

I deleted these packages from the OOB cache and tried after a while
and it worked. However, shouldn't we check for rpm package integrity
(content-type) while downloading via pycurl/libcurl and move to
another mirror in case of corruption or inconsistent file-type?
