Create the altix project branch. The altix project will add support

for the SGI Altix 350 to FreeBSD/ia64. The hardware used for porting
is a two-module system, consisting of a base compute module and a
CPU expansion module. SGI's NUMAFlex architecture can be an excellent
platform to test CPU affinity and NUMA-aware features in FreeBSD.

-.Sh NAME
-.Nm adduser
-.Nd command for adding new users
-.Sh SYNOPSIS
-.Nm
-.Op Fl CDENShq
-.Op Fl G Ar groups
-.Op Fl L Ar login_class
-.Op Fl M Ar mode
-.Op Fl d Ar partition
-.Op Fl f Ar file
-.Op Fl g Ar login_group
-.Op Fl k Ar dotdir
-.Op Fl m Ar message_file
-.Op Fl s Ar shell
-.Op Fl u Ar uid_start
-.Op Fl w Ar type
-.Sh DESCRIPTION
-The
-.Nm
-utility is a shell script, implemented around the
-.Xr pw 8
-command, for adding new users.
-It creates passwd/group entries, a home directory,
-copies dotfiles and sends the new user a welcome message.
-It supports two modes of operation.
-It may be used interactively
-at the command line to add one user at a time, or it may be directed
-to get the list of new users from a file and operate in batch mode
-without requiring any user interaction.
-.Sh RESTRICTIONS
-.Bl -tag -width indent
-.It username
-Login name.
-The user name is restricted to whatever
-.Xr pw 8
-will accept.
-Generally this means it
-may contain only lowercase characters or digits but cannot begin with the
-.Ql -
-character.
-Maximum length
-is 16 characters.
-The reasons for this limit are historical.
-Given that people have traditionally wanted to break this
-limit for aesthetic reasons, it has never been of great importance to break
-such a basic fundamental parameter in
-.Ux .
-You can change
-.Dv UT_NAMESIZE
-in
-.In utmp.h
-and recompile the
-world; people have done this and it works, but you will have problems
-with any precompiled programs, or source that assumes the 8-character
-name limit, such as NIS.
-The NIS protocol mandates an 8-character username.
-If you need a longer login name for e-mail addresses,
-you can define an alias in
-.Pa /etc/mail/aliases .
-.It "full name"
-This is typically known as the gecos field and usually contains
-the user's full name.
-Additionally, it may contain a comma separated
-list of values such as office number and work and home phones.
-If the
-name contains an ampersand it will be replaced by the capitalized
-login name when displayed by other programs.
-The
-.Ql \&:
-character is not allowed.
-.It shell
-Unless the
-.Fl S
-argument is supplied only valid shells from the shell database
-.Pq Pa /etc/shells
-are allowed.
-In addition,
-either the base name or the full path of the shell may be supplied.
-.It UID
-Automatically generated or your choice.
-It must be less than 32000.
-.It "GID/login group"
-Automatically generated or your choice.
-It must be less than 32000.
-.It password
-You may choose an empty password, disable the password, use a
-randomly generated password or specify your own plaintext password,
-which will be encrypted before being stored in the user database.
-.El
-.Sh UNIQUE GROUPS
-Perhaps you are missing what
-.Em can
-be done with this scheme that falls apart
-with most other schemes.
-With each user in their own group,
-they can safely run with a umask of 002 instead of the usual 022
-and create files in their home directory
-without worrying about others being able to change them.
-.Pp
-For a shared area you create a separate UID/GID (like cvs or ncvs on freefall),
-you place each person that should be able to access this area into that new
-group.
-.Pp
-This model of UID/GID administration allows far greater flexibility than lumping
-users into groups and having to muck with the umask when working in a shared
-area.
-.Pp
-I have been using this model for almost 10 years and found that it works
-for most situations, and has never gotten in the way.
-(Rod Grimes)
-.Sh CONFIGURATION
-The
-.Nm
-utility reads its configuration information from
-.Pa /etc/adduser.conf .
-If this file does not exist, it will use predefined defaults.
-While this file may be edited by hand,
-the safer option is to use the
-.Fl C
-command line argument.
-With this argument,
-.Nm
-will start interactive input, save the answers to its prompts in
-.Pa /etc/adduser.conf ,
-and promptly exit without modifying the user
-database.
-Options specified on the command line will take precedence over
-any values saved in this file.
-.Sh OPTIONS
-.Bl -tag -width indent
-.It Fl C
-Create new configuration file and exit.
-This option is mutually exclusive with the
-.Fl f
-option.
-.It Fl d Ar partition
-Home partition.
-Default partition, under which all user directories
-will be located.
-The
-.Pa /nonexistent
-partition is considered special.
-The
-.Nm
-script will not create and populate a home directory by that name.
-Otherwise,
-by default it attempts to create a home directory.
-.It Fl D
-Do not attempt to create the home directory.
-.It Fl E
-Disable the account.
-This option will lock the account by prepending the string
-.Dq Li *LOCKED*
-to the password field.
-The account may be unlocked
-by the super-user with the
-.Xr pw 8
-command:
-.Pp
-.D1 Nm pw Cm unlock Op Ar name | uid
-.It Fl f Ar file
-Get the list of accounts to create from
-.Ar file .
-If
-.Ar file
-is
-.Dq Fl ,
-then get the list from standard input.
-If this option is specified,
-.Nm
-will operate in batch mode and will not seek any user input.
-If an error is encountered while processing an account, it will write a
-message to standard error and move to the next account.
-The format
-of the input file is described below.
-.It Fl g Ar login_group
-Normally,
-if no login group is specified,
-it is assumed to be the same as the username.
-This option makes
-.Ar login_group
-the default.
-.It Fl G Ar groups
-Space-separated list of additional groups.
-This option allows the user to specify additional groups to add users to.
-The user is a member of these groups in addition to their login group.
-.It Fl h

-Set default login class.
-.It Fl m Ar file
-Send new users a welcome message from
-.Ar file .
-Specifying a value of
-.Cm no

-file can reference the internal variables of the
-.Nm
-script.
-.It Fl M Ar mode
-Create the home directory with permissions set to
-.Ar mode .
-.It Fl N
-Do not read the default configuration file.
-.It Fl q
-Minimal user feedback.
-In particular, the random password will not be echoed to
-standard output.
-.It Fl s Ar shell
-Default shell for new users.
-The
-.Ar shell
-argument may be the base name of the shell or the full path.
-Unless the
-.Fl S
-argument is supplied the shell must exist in
-.Pa /etc/shells
-or be the special shell
-.Em nologin
-to be considered a valid shell.
-.It Fl S
-The existence or validity of the specified shell will not be checked.
-.It Fl u Ar uid
-Use UIDs from
-.Ar uid
-on up.
-.It Fl w Ar type
-Password type.

-.Nm
-utility allows the user to specify what type of password to create.
-The
-.Ar type
-argument may have one of the following values:
-.Bl -tag -width ".Cm random"
-.It Cm no
-Disable the password.
-Instead of an encrypted string, the password field will contain a single
-.Ql *
-character.
-The user may not log in until the super-user
-manually enables the password.
-.It Cm none
-Use an empty string as the password.
-.It Cm yes
-Use a user-supplied string as the password.

-last (10th) field in the line is assumed to be the password.
-.It Cm random
-Generate a random string and use it as a password.
-The password will be echoed to standard output.
-In addition, it will be available for inclusion in the message file in the
-.Va randompass
-variable.

-All other lines must contain ten colon
-.Pq Ql \&:
-separated fields as described below.
-Command line options do not take precedence
-over values in the fields.
-Only the password field may contain a
-.Ql \&:
-character as part of the string.

-and this field is
-.Em not
-empty, its contents will be used
-as a password.
-This field will be ignored if the
-.Fl w
-option is used with a
-.Cm no
-or
-.Cm none
-argument.
-Be careful not to terminate this field with a closing
-.Ql \&:
-because it will be treated as part of the password.

-.Sh HISTORY
-The
-.Nm
-command appeared in
-.Fx 2.1 .
-.Sh AUTHORS
-.An -nosplit
-This manual page and the original script, in Perl, was written by
-.An Wolfram Schneider Aq wosch@FreeBSD.org .
-The replacement script, written as a Bourne
-shell script with some enhancements, and the man page modification that
-came with it were done by
-.An Mike Makonnen Aq mtm@identd.net .
-.Sh BUGS
-In order for
-.Nm
-to correctly expand variables such as
-.Va $username
-and
-.Va $randompass
-in the message sent to new users, it must let the shell evaluate
-each line of the message file.
-This means that shell commands can also be embedded in the message file.
-The
-.Nm
-utility attempts to mitigate the possibility of an attacker using this
-feature by refusing to evaluate the file if it is not owned and writable
-only by the root user.
-In addition, shell special characters and operators will have to be
-escaped when used in the message file.
-.Pp
-Also, password ageing and account expiry times are currently settable
-only in batch mode or when specified in
-.Pa /etc/adduser.conf .
-The user should be able to set them in interactive mode as well.
