ok, part of my problem is not understancing how much linux lies to me.
after a reboot, it does show 95% full.
but doing the math on the blocks used/total,
it is technically under 90% full, and what it tells me is "available" is 5%, so the difference is being withheld from me. unless those numbers are innacurate or there is some basic issue I don't understand.
I don't know enough of the internal workings to know if that is reasonable, or a holdover from when disks were smaller.
if it is more than reasonable, the problem is that I could get to ignore the "disk almost full" warnings even when it really is almost full.
By default, an ext filesystem will reserve 5% of its capacity. So you are seeing 5% free + 5% reserved, comes out to the 10% you are looking for. [snip]
