What sets the size of the
tmpfs? (On my machine it resides in
I can see its entry in
/etc/fstab, but no notation of its size.
When checking with
df -h, it seems to be half the size of the physical memory installed in the system.
Is this the default behavior?
Also, what happens if it gets full? Does it expand dynamically forcing other running programs into
tmpfs itself moves into
Finally, what takes priority into the memory
tmpfs or applications? i.e., if I have
tmpfs sufficiently full (like 40% of the physical memory) and I have programs that requires 70% of the physical memory, which one gets the priority?
