FuguIta 7.1 changes from TMPFS to MFS as a memory-based file system.
This will result in the following changes
The automatic specification of file capacity that existed in TMPFS does not exist in MFS. You will have to specify it explicitly.
The maximum amount of files that can be held in memory will be a little over 1GB on the i386 platform and a little over 30GB on amd64. This is a limit of MFS itself, and the value is independent of the page-out to the swap partition.
