Meta Configuration of Package dosemu

<package name="dosemu" project="openSUSE:Backports:SLE-15-SP5">
  <title>The DOS Emulator</title>
  <description>This package allows MS-DOS programs to be run in Linux. A virtual
  machine (the DOS box) provides the necessary BIOS functions and
  emulates most of the chip devices (for example: timer, interrupt, and
  keyboard controller).

Documentation can be found in /usr/share/doc/packages/dosemu, the man
  page, and in the sources.

Starting with version 1.0.2, DOSEMU configuration files are no longer
  in /etc but in the user's HOME directory in ~/dosemu. DOSEMU no longer
  has the SUID bit set, so if you need access to hardware that requires
  root privileges, you must run DOSEMU as root.

If you rely on the old configuration scheme, you can get it back by
  using dosemu.bin instead of dosemu (dos and xdos have been renamed to
  dosemu and xdosemu).

The parameter $_hogthreshold in ~/dosemu/conf/dosemu.conf defines how
  often an idling DOSEMU should return the CPU to Linux and its default
  value (1) means "all power to Linux." The higher this value is, the
  more CPU power is dedicated to DOSEMU. The value (0) disables this
  feature completely, hence: "all power to DOSEMU." If that is not fast
  enough, you (running as UID root) can get maximum performance with

nice -19 dos -D-a 2&gt;/dev/null

Do not be surprised if other Linux processes then run very sluggishly.

On sensitive systems, you should never offer an suid-root DOSEMU as
  world readable. Even if the '$_secure' option in dosemu.conf is set, it
  is still possible that some DPMI clients (most likely Dos4gw based
  ones) may succeed in accessing the whole user space (including DOSEMU
  code) and thus gain root access. A comfortable solution is to have two
  copies of the DOSEMU binary, a non-suid-root one for world access and a
  suid-root one (protected by file permissions) only available to trusted
  users.</description>
