Add -D flag to allow the user to specify an alternate dumpdates file.
Closes PR #54469.

Bump date for previous.

Add -U flag to dump(8) and dump_lfs(8) to specify dumpdates entry

This address situations where dump(8) cannot figure out the device being
dumped. It also allows tracking of subvolume dumps by using virtual
device as dumpdates entry.

Document what rdump is (was once) for. PR 53442.

dump was there from v4.
Confirmed from the TUHS hosted copies of man pages.
Bump date.

Default the read block size (-k default value) to kern.maxphys (usually
64k these days). This gives a noticable performance boost on large filesystems.

Snapshot support for dump(8):

- New option `-x backup' takes the dump from a snapshot backed up by `backup'.
The snapshot will be deleted on exit.

- New option `-X' as a synonym for `-x mountpoint' where `mountpoint' is the
file system to be dumped.

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22308, verified by myself.

* Document $RCMD_CMD in environ(7).
* Cross-reference rcmd(1), rcmd(3), and environ(7) as appropriate.

Should fix [bin/21670] from Geoff Wing.

Use "wall -g operator" (instead of private code) to broadcast() messages to
members of the operator group.
Don't install "setgid tty", and remove now unnecessary gid/egid swapping.
Remove utmp trawling code pulled in from usr.bin/who.
The Code is now simpler, and more portable (without the utmp cruft) too.

This is derived from similar work in OpenBSD.

.Nm does not need a dummy argument ("") before punctuation or
for correct formatting of the SYNOPSIS any longer.

"Utilize" has exactly the same meaning as "use," but it is more
difficult to read and understand. Most manuals of English style
therefore say that you should use "use".

New sentence, new line. By Robert Elz with minimal fixes.

Typo fix, from jslag@prop.walkerart.org via OpenBSD.

Fix typo in macro.

For -l: specify the timeout on the command line (in seconds) instead of
hardwiring it to 2s, as suggested on tech-userlevel.

Add -a to "auto-size" the tape, rather than relying upon other options
to define the tape size. Requires the tape driver to either return ENOSPC
at end of media, or 0 when a write is attempted (such as the "early warning"
support in st(4) enabled with "mt eew 1"). From FreeBSD.

Add a -l (autoload) flag. For multivolume dumps, this makes dump eject the
tape when a volume is full, and try to reopen the tape drive for 2 mn.
To be used with tape changers which load the next tape when the current one is
ejected.
While I'm there fix eject handling for remote tape.

One '\' too many.

relax the restriction on -F that the file system image argument must be a
regular file

Whitespace fixes, sort SEE ALSO, sort sections.

Add the capability for dump to print timestamps on all informational
messages.

- implement -F, which indicates that files-to-dump is a regular file
containing a file system image (instead of being a single file as
part of a subtree dump)
- use "file system" instead of "filesystem" or "file-system"

Drop arguments of .Os.

* improve parsing of file-systems-to-dump when a path is given:
- if it's a path to an unmounted file-system listed in /etc/fstab, use
that instead of assuming the user wanted a subtree dump of the parent
directory. this restores the behaviour of dump before the subtree
dumping code went in.
- if it's a path to a mounted file-system which is not in /etc/fstab,
use the info from getmntinfo(3). previously, dump would choke.
* implement error checked malloc(), calloc(), strdup(), and use
appropriately (some of the calloc()s weren't being checked)
* use 'file-system' instead of 'filesystem' in the man page

Add a new option "e" to "dump" which allows to eject tapes automatically
if a tape change is required.

Note the default tape device is taken from _PATH_DEFTAPE in /usr/include/paths.h

Implement a read cache, as announced on tech-userlevel. Default is 32k
read buffer size, 512 buffer or 15% of the user memory. Can be changed
with the -k and -s options.

Handle "nodump" flag on directories, by not dumping any files or directories
under it. Based on some parts of PR 6705 by Brian Grayson.
In the Makefile, add (commented out) debug options that can be turned on.

Clean up SYNOPSIS formatting.

s/1998/1999/

add support for '-L label', which file(1) and restore(1) can extract
from the header.
mostly based on [bin/6715] from Brian Grayson <bgrayson@ece.utexas.edu>

Add reference to "st(4)" as suggested by Brian Grayson in PR bin/6713.

A dump level above 0 saves new or modified files since the last dump of
a lower level, not the same level. Fixes pr 5402 by Kevin Sullivan.

Fix .Nm usage.

Various changes from Brian Grayson <bgrayson@ece.utexas.edu> in [bin/4103]
* exit after providing an estimate if -S was given. the PR used -e,
but checking around indicated prior art in Solaris usin -S.
* remove superfluous 'DUMP:' prefix in two messages
* initialise blocksperfile explicitly (not necessary, but everything
else in that section gets initialised, so be consistant :)
* display the ``pretty'' name of the dumped directory, so the user
knows if it's a subset or not

resolve conflicts from lite-2 import

* cleanup for WARNS=1
* fix use of .Nm
* comment out some unused(?) functions

cleanup xrefs

* Add the ability to dump specific files & directories of a single
filesystem. This uses fts(3) to access the directory structure (and
not the raw device), so the standard access permissions are adhered
to (unlike dumping an entire filesystem, which just requires read
access to the raw disk device).
* Support SIGINFO status reporting.
* Remove now unused variables that previously stored the (e)uid.
* Be more informative in a couple of error messages.

use _PATH_DEFTAPE from <paths.h>
