[Cooker] No kernels on uninett ?

[Frank Griffin]

I resync'd cooker with ftp.uninett.no about an hour ago, and found that 
all of my .15 kernels were deleted with no replacements.  Sure enough, 
all of the cooker kernel files (except for the docs) are gone from the 
mirror.

I've continued to check over the past hour, so this isn't a case of an 
update in-flight.
