For this to work, the rump kernel must include the vfs faction,
since the module is loaded using kernel vfs code (see
.Sx EXAMPLES ) .
.It Fl r Ar total_ram
Sets the limit of kernel memory allocatable by the server to
.Ar total_ram
as opposed to the default which allows the server to allocate as much
memory as the host will give it.
This parameter is especially useful for VFS servers, since by
default the virtual file system will attempt to consume as much
memory as it can, and accessing large files can cause an excessive
amount of memory to be used as file system cache.

Do not detach from the terminal.
