we should also have a bit of free space on the ramdisk filesystem
since there are places where tmp files are created and such.

if it were 1024 bytes or less compressing wouldn't matter, becaues of
block sizes,  but if we can take 6000 bytes down to 1000 or so we
savea  few blocks..   whatever which ever way makes the most sense.
we need some free space on the uncompressed root filesystem too.
