Thanks for the answer, but that is more or less just the same as to
add -osize=32M to each and every mountpoint. I'm searching for a
variable to change the defaultvalue. And if that does not exist I
would suggest it should be added as TMPFS_SIZE=50% to

I want to be able to easily upgrade the kernel when a new one is
distributed thru (main). If I build my own there will be a lot of
trouble, or at least a lot of extra work, when I want to upgrade.
But as the server-kernel is compiled I don't think I have much of a
choise. There is ALOT of desktop-stuff in the server-kernel, like
laptop specific things and such. But that is off-topic in this thread.
