Add a noupdate option to the opkg script to try
updating the packages without actually running an
update (maybe we already have the latest lists)
Tweak the maint and timing for it to temporarily push
fixed manager binary.
In opkg-1, install on BTS0 in order
to download the packages before copying them to the
local system.
Optionally, instead of running opkg update on each BTS, just
run on the master, then copy all the list and cached pkg files
to each bts.
This can help if the IP connection is so bad we have trouble
downloading opkg file from the server.
