remove threads; size constraints and behavioral change

Add -lpthread for the benefit or argon2 in cgdconfig

remove SMBFS and nsmb/netsmb - userland part

Retire lmcconfig here too.

Remove the userland part of ISDN. The kernel part is untouched for now.
ipppctl was actually an exact copy of pppoectl; there is no functional
change in pppoectl in this commit.

Add a port of the umb(4) driver from OpenBSD

The umb(4) driver provides support for USB MBIM (Mobile Broadband
Interface Model) devices.

MBIM devices establish connections via cellular networks such as GPRS,
UMTS, and LTE. They appear as a regular point-to-point network interface, transporting raw IP frames.

Required configuration parameters like PIN and APN have to be set with
umbctl(8), a new tool specific to this driver. The IP address is configured
automatically; the default route and DNS server information have to be set
separately.

The driver is not fully functional yet, it is therefore still marked as
experimental and disabled by default. Any help welcome to complete it!

Tested on NetBSD/amd64, with a Sierra Wireless EM7345 LTE modem on a Lenovo
ThinkPad T440s. No functional change expected otherwise.

Add progress(1) into /rescue.

No objection when proposed on tech-userlevel@.

vnconfig(8) was renamed to vndconfig(8) some time ago, and most places
keep both names around.

One place that got missed is /rescue so let's update it for consistency
with all the other places.

(Pointed out in private Email by kre@)

branches: 1.47.2;
cgdconfig is not crypto

Add rescue/ekermit.

mount_smbfs has moved.

nvi has moved

Update location of "less" directory.

add the lzma library now that is used by gzip

branches: 1.40.4;
Adjust for the new chown location.

Don't install terminfo.db.

Move the emergancy terminfo database from /root to /rescue.

Userland now builds and uses terminfo instead of termcap.

OK: core@, jdc@

Remove the portalfs kernel file system driver. Replace mount_portal(8)
with a version based on puffs. User functionality remains the same.

- rework this a bunch to make it work inside /rescue/ldd.
- fix alpha build.

Remove LKMs and switch to the module framework, pass 1.

Proposed on tech-kern@.

branches: 1.33.2;
use nvi instead. thanks to Andreas Wrede

Remove systrace. Ok core@.

branches: 1.31.4;
Add read-only support for SGI's Extent File System.

Reviewed by pooka@.

Add dumpfs & dumplfs to /rescue, as they may be useful during system
recovery.

Add: lfs_cleanerd
Suggested by Blair Sadewitz

Add: grep egrep fgrep zgrep zegrep zfgrep
Suggested by George Michaelson

add libprop to LIBS, as veriexecctl now needs it.

Revert the recent addition of /rescue/gkermit. There's some concern
that linking GPL code into /rescue is not a good idea.

Add /rescue/gkermit. Discussed in tech-userlevel.

Add mount_tmpfs(8) to /rescue. Ok with christos.

Add ex(1) to /rescue. This won't add more than a few bytes to the crunchgen
binary since "ex" is just "vi -e" and vi(1) is already there.

Ok with hubertf and salo.

branches: 1.23.2;
lmcctl has been replaced by lmcconfig.

put back tetris; by popular demand.

PR/31370: Andreas Wiese: Remove tetris from rescue

Add vnconfig(8). ok christos

add scan_ffs and veriexecctl to /rescue

Make fdisk(8) available on all platforms, since MS-DOS partitioning
is the de-facto standard for many removable media types.

Add /rescue/tetris.
When your system is fubared, this will help you relax.

cosmetic tweak

Restore the "liboverride" functionality because it's needed to correctly
implement rmcd(3) in the rescue tools.

Add: less (more), vi, chroot
Requested by Matthew Mondor in PR 26147

Only compile in IPv6 support if ${USE_INET6} != "no"

MKINET6 is for providing IPv6 infrastructure.
USE_INET6 is for compiling IPv6 support into the programs (needs MKINET6).

Complete removal of "liboverride" to fix build problems.

no need to list gnu/usr.bin any more.

add mount_smbfs

systrace needs libevent now.

Add installboot. Suggested by Curt Sampson.

* Add ftp to /rescue.
* Implement liboverride.o to provide overrides of various libc functions.
For now, compile a special version of rcmd(3) (et al) which uses
/rescue/rcmd and /rescue/sh instead of the /bin variants.
Other overrides may appear in the future.

Should fix [bin/21670] from Geoff Wing.

Build mount_* individually, since mount and most of mount_* no longer
shares binary image. Fixes PR#20553.

Add chown and chgrp. Suggested by Geoff Wing in [bin/18393]

oops; typo. (thanks enami!)

don't install -sh as a link to sh. use ARGVLN to support -sh, -csh, and -ksh

support -sh as a synonym for sh

Migrate rescue tools from distrib/rescue -> rescue. Purpose of tools:

Infrastructure to build a set of "rescue" tools; a crunched-up
version of all the statically linked binaries in /bin, /sbin
and the few in /usr/bin.
