Hey folks!
I'm doing some %pre work for the first time in a very long time, and
have been at this all day so far and still don't have anything sorted
out properly.
First I tried just doing some simple bash stuff like this
%pre
#!/bin/bash
# stuff
I reduced "stuff" down to basically a simple "select"
statement to
echo and read input, just for the sake of debugging.
My first problem is that when running the kickstart, the little box
would come up saying it is running the pre scripts, but my scripts
would never actually run. No output, no prompts, nothing.
So after some muddling I tried this :
%pre
#!/bin/bash
exec 1>&3
exec > /dev/tty
chvt 3
exec < /dev/tty3 > /dev/tty3
clear
# stuff
I cannot say I really understand this - it is just something I came
across. in any case, now my script seems to run fine, but after it
finishes it does not appear to go back to my install. I get messages
like :
date INFO all kickstart %%pre script(s) have been run
date WARNING resolution and depth not specified, try to be sane
and that is it - it stops there.
I've also tried just :
%pre
#!/bin/bash
chvt 3
clear
# stuff
With the same results as above.
This is all running within VMWare ESXi 4.0 if that matters.
What am I missing here?
thanks,
-Alan

Tested this under ESX 4.0 this morning. This is what my %pre looks like now, I consolidated all configs into a single script that is called # Note: there doesn't seem to be any way to log stuff that occurs in %pre as # it occurs outside of the chroot before kickstart loads. %pre export KICKSTART_IP=`cat /proc/cmdline | sed s'/.*http:\/\///'g | sed s'/\/config.*//'g` wget http://${KICKSTART_IP}/kickstart-postinstall/bin/kickstart-pre-install-generic.sh -O /tmp/kickstart-pre-install-generic.sh chmod 755 /tmp/kickstart-pre-install-generic.sh /tmp/kickstart-pre-install-generic.sh then the kickstart-pre-install-generic.sh script contains #!/bin/sh export KICKSTART_IP=`cat /proc/cmdline | sed s'/.*http:\/\///'g | sed s'/\/config.*//'g` export KERNEL_VERSION=`uname -r` # No /etc/redhat-release during pre, so guessing based on kernel version echo $KERNEL_VERSION | grep "2.6.9" && export CURRENT_OS="RHEL4" echo $KERNEL_VERSION | grep "2.6.9" || export CURRENT_OS="RHEL5" ############################################################################### ## Attempt to auto detect console device ## ############################################################################### grep -q "ttyS0,9600" /proc/cmdline && wget http://${KICKSTART_IP}/config/common/rhel_5/console/console_ttyS0_9600.cfg -O /tmp/console.config grep -q "ttyS0,57600" /proc/cmdline && wget http://${KICKSTART_IP}/config/common/rhel_5/console/console_ttyS0_57600.cfg -O /tmp/console.config grep -q "ttyS0,115200" /proc/cmdline && wget http://${KICKSTART_IP}/config/common/rhel_5/console/console_ttyS0_115200.cfg -O /tmp/console.config grep -q "ttyS1,9600" /proc/cmdline && wget http://${KICKSTART_IP}/config/common/rhel_5/console/console_ttyS1_9600.cfg -O /tmp/console.config grep -q "ttyS1,57600" /proc/cmdline && wget http://${KICKSTART_IP}/config/common/rhel_5/console/console_ttyS1_57600.cfg -O /tmp/console.config grep -q "ttyS1,115200" /proc/cmdline && wget http://${KICKSTART_IP}/config/common/rhel_5/console/console_ttyS1_115200.cfg -O /tmp/console.config # Default to VGA if we can't find a serial console defined [ ! -f "/tmp/console.config" ] && wget http://${KICKSTART_IP}/config/common/rhel_5/console/vga.cfg -O /tmp/console.config ############################################################################### ## Attempt to auto detect network device ## ############################################################################### [ "$CURRENT_OS" == "RHEL5" ] && grep -q "ksdevice=eth0" /proc/cmdline && wget http://${KICKSTART_IP}/config/common/rhel_5/network/ksdevice_eth0.config -O /tmp/network.config [ "$CURRENT_OS" == "RHEL5" ] && grep -q "ksdevice=eth1" /proc/cmdline && wget http://${KICKSTART_IP}/config/common/rhel_5/network/ksdevice_eth1.config -O /tmp/network.config echo $KERNEL_VERSION | grep "2.6.9" && grep -q "ksdevice=eth0" /proc/cmdline && wget http://${KICKSTART_IP}/config/common/rhel_4/network/ksdevice_eth0.config -O /tmp/network.config echo $KERNEL_VERSION | grep "2.6.9" && grep -q "ksdevice=eth1" /proc/cmdline && wget http://${KICKSTART_IP}/config/common/rhel_4/network/ksdevice_eth1.config -O /tmp/network.config # Default to eth0 if we don't see anything specified [ "$CURRENT_OS" == "RHEL5" ] && [ ! -f "/tmp/network.config" ] && wget http://${KICKSTART_IP}/config/common/rhel_5/network/ksdevice_eth0.config -O /tmp/network.config echo $KERNEL_VERSION | grep "2.6.9" && [ ! -f "/tmp/network.config" ] && wget http://${KICKSTART_IP}/config/common/rhel_4/network/ksdevice_eth0.config -O /tmp/network.config ############################################################################### ## Attempt to auto detect custom swap size ## ############################################################################### grep -qi "swapsize" /proc/cmdline && export SWAPSIZE=`cat /proc/cmdline | sed s'/ /\n/'g | grep swapsize | sed s'/swapsize=//'g` [ -z "$SWAPSIZE" ] && export SWAPSIZE="4096" echo "part swap --size=${SWAPSIZE}" >/tmp/swap.config -- end script -- nate
