Is /bin/bash even available during %pre ?

I just started testing CentOS 5.4 yesterday w/kickstart, currently
all of my systems are 5.2. 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"
