output from mount(8) rather than df(1), because mount is more likely
to be available on install media. mount is invoked in a way that
always prints an error message, and the content of the error message
tells us whether fdesc is mounted. This should fix PR 40316 from
David Ross.
* Don't use negative variable names. Instead of nofdesc=false, use
fdesc_mounted=true.
* Add a comment explaining that MAKEDEV may be executed in an environment

already-existing device nodes. This is done by invoking pax with its
current working directory set to an empty temporary directory.
* Add "-t mtree" command line option, to force MAKEDEV to use "mtree

${method} all" on an i386 system; each method was executed three
times, first in an empty directory, then twice in an already-populated
directory:

mknod, in that order of preference.
No objections in tech-userlevel to an earlier version of this change.
"retro" computers, but NetBSD also runs a growing number of rare
and retro add-on cards. With this patch, NetBSD supports the IDEC
Supervision/16, a black&white image capture board for the 16-bit
ISA bus. Approximate date of manufacture: 1991. Total instances
known to be in use throughout the world: one.
Coming soon; isvctl(8), the utility program for capturing 8-bit,

This is so that md code that tries to call makedev altq or fd does not fail
when the file exists. This was reported in port-powerpc, when building /dev.
* Add a nooutput function to be used instead of redirecting to /dev/null,
because /dev/null might not exist early in the boot sequence. This
should fix a bug in which the pax autodetection failed when used from
init(8) with a read-only root file system without a /dev/null.
* Move most of the main program into a new makedev_main function,
to allow reuse by MAKEDEV.local.
In MAKEDEV.local:
* Use the new makedev_main function defined in MAKEDEV. This allows
MAKEDEV.local to support all the options understood by MAKEDEV, instead
of only a subset. This should fix a bug in which the setup() function
could try to use pax mode even though that was previously not supported.
In MAKEDEV.local man page:
* Update list of command line options.
* Don't explain all the options, just refer to MAKEDEV(8) man page.
* Remove BUGS section now that all MAKEDEV options are supported
by MAKEDEV.local.
Improve the documentation around that.
* The "-p pax", "-m mknod", and "-s" (mtree specfile) options should
always have been mutually exclusive. Now enforce that.
* The "-f" option didn't ever work with pax or mtree mode; document that,
and make it an error to try something that won't work.
* Make pax mode the default, if no other options prevent this, and if
"pax -w -M" appears to be usable.
* Add missing options to a usage message.

* One "-M" flag will create the mfs file system but not redirect output
