For what is worths, with the increasing size of the builds I had posted [1] a crude script I was using to remove dri, firmware, extra locales and 256x256 ions (61Mb worth on os874) which people used, and I did not hear any complains, yet ;).

Going back to the issue of size, it would appear that in os1 tmpfs size (114MB)  is subtracted from the available storage. 
Thus even if os1 is ~660MB the free space is only 270MB, since /dev/ubi0_0 is only 898MB instead on 1024M (for mtdblok0) in os874.
Is this something specific to ubifs or a configuration issue?
