:Hi !
:
:1. What is the maximum size of a file on a filesystem ?
:2. What is the maximum size of a filesystem ?
:3. What is the maximum amount of RAM that FreeBSD can handle ?
:4. What is the maximum size of a file that can be mmap´ed ?
:
:Furthermore, I understand that FreeBSD can´t mmap a block device.
:Is it planned to change that ?
:
:Thanks ! :-)

The maximum size of a standard filesystem is 8 Terrabytes.
The maximum size of a file depends on the filesystem. It is 8 Terrabytes
on the standard UFS filesystem.
FreeBSD boxes can handle up to 4 Gigabytes of main memory.
Block devices are being removed from the system so the answer is
no at the moment. If people have a need, we will probably introduce
a block device overlay of some sort that would theoretically be mmapable.
