I'm trying to kickstart a Centos 4.1 system with the minimum set of packages. I have no use for ypbind so I'm trying to prevent from being installed, but kickstart/anaconda always insist on its installation (complaining that the package is missing). This is the %packages section of my ks file so far: %packages #-@ dialup kernel grub e2fsprogs lvm2 -slocate -bluez-utils -bluez-bluefw -bluez-hcidump-1.11-1.i386.rpm -isdn4k-utils -pcmcia-cs -ppp -wvdial -ypbind as you can see, ypbind is deselected in the ks file. Is ypbind a mandatory package? In the RPMS directory, I tried to determine what package may be requiring ypbind, but I could find any. This is what I used to determine what package may be requiring it: cd CentOS/RPMS for i in *.rpm; do echo ---------------- $i; rpm -qp --requires $i 2>/dev/null | grep ypbind && echo ******** $i *******;done
