Hi folks,
Please review the attached (short) port of mdmfs, a program with a
mount_mfs(8)-like interface to md(4). It creates, labels, newfs's,
and mounts a memory disk using md(4). Its purpose is primarily
backwards-compatiblity with mount_mfs; it offers no new features. It
passes portlint with no warnings or errors.
Thanks in advance,
Dima Dorfman

XThe memory filesystem (MFS) no longer exists in FreeBSD-CURRENT. It
Xwas deprecated in favor of the memory disk driver (md(4)), which can
Xnow support swap-backed, malloc-backed, and vnode-backed disks. The
Xonly downside is that the syntax for mounting an equivalent to an MFS
Xusing md(4) is incompatible with the old syntax. The new syntax is
Xmuch more powerful, but occasionally backwards compatibility is
Xdesired. This program attempts to provide a mount_mfs(8) interface to
Xmd(4) and friends.

XThe following excerpt from the manual page, mdmfs(8), sums it up:
X
X The mdmfs program is designed to be a work-alike and look-alike of the
X deprecated mount_mfs(8). The end result is essentially the same, but is
X accomplished in a completely different way. mdmfs configures an md(4)
X disk using mdconfig(8), labels it using disklabel(8), puts a UFS filesys-
X tem on it using newfs(8), and mounts it using mount(8). All the command
X line options are passed to the appropriate program at the appropriate
X stage in order to achieve the desired effect.
X
XThis program provides nothing in the way of new features; it is simply
Xa mount_mfs(8) interface to md(4). If you don't need this backwards
Xcompatibility, you probably don't want to install this.
