    Hi,
    I have found a small bug in the /usr/sbin/dupatch delivered as part of 5.1.b PK4.
    The version is
    # @(#)$RCSfile: dupatch.sh,v $ $Revision: 1.1.2.56 $ (DEC) $Date: 2004/06/07 14:40:21 $

    and the problem is the following function:

    FitsetSetup()
    {
            PWD=`pwd`

            DEF_USRRSV=40960
            DEF_ROOTRSV=15360

            DUK=
            HOSTNAME=`/usr/sbin/rcmgr get HOSTNAME`
            [ "$HOSTNAME" ] &&
            {
                    HOSTNAME=`Parse . $HOSTNAME | awk '{print $1}'`
                    HOSTNAME=`Ucase $HOSTNAME`
                    [ -d /usr/sys/$HOSTNAME ] &&
                    {
                            cd /usr/sys/$HOSTNAME
                            DUK=`du -sk . | awk '{print $1}'`
                    }
            }
            DUK=`expr $DUK \* 2`
            USRRSV=`FitsetReserve $DEF_USRRSV $DUK`

            DUK=
            [ -f /vmunix ] &&
            {
                    cd /
                    DUK=`du -sk vmunix | awk '{print $1}'`
            }
            ROOTRSV=`FitsetReserve $DEF_ROOTRSV $DUK`

            cd $PWD

    }

    Here DUK is first set to "" and it is only if /usr/sys/$HOSTNAME exists that it get
    changed to something else. The hostname on the machine I am patching has been changed
    and I do not have /usr/sys/$HOSTNAME, only /usr/sys/$THE_OLD_HOSTNAME, so the result
    is that the statement
    DUK=`expr $DUK \* 2`
    fails with a syntax error.

    I can fix this problem in various ways, e.g. rename /usr/sys/$THE_OLD_HOSTNAME to
    /usr/sys/$HOSTNAME or simply set DUK to something sensible in the script, but I
    would like to know if there is any "correct" way of doing this (or if there are
    any gotchas).
