Will 2.1 offer any option to change size of ram drives.
Not that I'm aware of, what are you needing to tweak the size for?
I have postfix and it and var runs out of space and postfix rejects all messages.
/dev/md1 58M 55M -1.9M 103% /var
So it means reboot time
Why are you running postfix on NanoBSD? Seems like a disaster waiting to happen…
Doesn't matter how much you increase the space of the ram disk if whatever is filling it up doesn't clean up after itself it will pile up and fill up the larger one, too
