Add the groupmod '-d' option to pw to allow the deletion of existing users
from a group without the need to perform the same operation by replacing
the existing list via the '-M' option. The '-M' option requires someone
to fetch the existing members with pw, deleting the undesired members from
the list and sending the altered list back to pw.

Add home directory creation mode to pw.conf(5) and be a bit
more specific about the effect of the current umask on -M.

Add -M argument to usage() output.

Introduce the new option -M to allow to set the permissions of
the user's newly created home directory. If omitted, it's derived
from the current umask.

Fix the type of the NULL arg to execl()

Idea from: Theo de Raadt <deraadt@openbsd.org>

Fix a harmless format string bogon and mark a function as __printflike().
There is still one instance of non-constant format string use inside that
function, but it's hard to fix.

Portability fixes for other bsd4.4 derivatives.

Add new functionality "lock" and "unlock" to provide a simple password
locking mechanism for users. This works by prepending the string
"*LOCKED*" to the password field in master.passwd to prevent successful
decoding.

$Id$ -> $FreeBSD$

Add the ability to print user records in unix version 7 (old) format.

Fix minor nit with command line parsing for pw -V DIR action.

Fix tpyo (sic) and missing 'else' (bad cut n' paste).

1) Do not blindly ignore file update errors which may occur due to concurrent
updating
2) Add -V <etcdir>, which allows maintaining user/group database in alternate
locations other than /etc.

Remove bogus file locking in main().

- On second thought, attempt to get the read-only lock, but don't
consider it a exit failure if it doesn't work. This means that root
processes can safely get the lock, but normal processes can still use
the 'pw' utility to get information (which may change out from under
them.)

- Removed read-only lock from 'pw'. This removes portions of the FIX
from PR/6787, but allow non-root users to use pw to get password
information. However, this should be safe since the fixes for
disallowing multiple instances from modifying the DB are still intact.

Bug noted by: dima@best.net (Dima Ruban)

Fix race condition in pw caused by multiple instances of pwd_mkdb being
run at the same time.

Notes:
The fileupdate function is still somewhat broken. Instead of
returning a failure code if it can't modify the original file it
renames the .new file and continues as though nothing is wrong.
This will cause the lock on the original file to be lost and could
lead to a similar race condition. I left that portion of the code
alone since I feel that the maintainer of the code would have a
better concept of how he wants to handle errors in that function
than I do.

2.2 candidate...

pw(8) -- a backend utility to manage the user and group databases.

sysinstall's new User&group menu will use it, hence it's a 2.2
candidate despite of providing new functionality.
