Hi,

I'm still working on qmail package. My script which adds necessary users & groups
now looks like:

#!/bin/sh
#
# $NetBSD$
#

PASSWDFILE=/etc/passwd

NOSHELL=/sbin/nologin

CHFN=/usr/bin/chfn
AWK=/usr/bin/awk
GREP=/usr/bin/grep
QMAILDIR=/var/qmail

create_group()
{
        GROUP=$1
        
        $GREP "^$GROUP" $GROUPFILE > /dev/null || (
                FREEGID=`$AWK -F: '{gids[$3]++}END{for (i=81;;i++) if (gids[i] == 0) {print i;exit 0}}' < ${GROUPFILE}`
                echo "$GROUP:*:$FREEGID:" >> /etc/group
        )

        return
}

create_user()
{
        NAME=$1

        if [ "$NAME" = alias ];  then
                HOME="$QMAILDIR/alias"
        else
                HOME="$QMAILDIR"
        fi

        ( id $NAME 2> /dev/null > /dev/null ) || ( 
                FREEUID=`$AWK -F: '{uids[$3]++}END{for (i=81;;i++) if (uids[i] == 0) {print i;exit 0}}' < ${PASSWDFILE}`
                GROUP=`$GREP $2 $GROUPFILE | $AWK -F: '{ print $4 }'`
                $CHFN -a $NAME:*:$FREEUID:$GROUP::0:0:$NAME:$HOME:/sbin/nologin
        ) && echo "user $NAME already exists, skipping addition"

        return
}

create_group qmail
create_group nofiles

create_user alias nofiles
create_user qmaill nofiles
create_user qmaild nofiles
create_user qmailp nofiles
create_user qmailq qmail
create_user qmailr qmail
create_user qmails qmail

Yes, it looks very dirty. I could use groupinfo instead of greping /etc/group,
but groupinfo does not exist on pre-1.5 systems. I was said that grep won't work in all cases,
for example when one uses NIS etc. For now, I see no good way to do it.

useradd appeared in NetBSD 1.5, too, thus I decided to use "chfn -a". But this forces me to find a free uid,
so I have to use awk.

Thoughts how to implement this better?
