Yes you can. Here's how I do it.
These are the pertinent lines from my
/tftpboot/linux-install/pxelinux.cfg/default file. Note the "rescue"
directive.
label 7
kernel rhel4r1/vmlinuz
append initrd=rhel4r1/initrd.img \
ramdisk_size=10000 \
rescue \
ks=http://10.20.2.3/kickstart/ks_rescue.cfg
(Note: the line continuations for readability. They are
not allowed in the actual file.)
This is the corresponding section in the
/tftpboot/linux-install/msgs/boot.msg file:
Rescue Modes:
5. RHEL 2.1 ES U4 Rescue Mode
6. RHEL 3 ES U4 Rescue Mode
7. RHEL 4 ES R1 Rescue Mode
Using the kickstart file is not required. It is for
convenience, answering most of the questions that get
asked:
# Kickstart configuration file RHEL 3 EL U4 Rescue Mode
#
#System language
#
lang en_US
#
#Language modules to install
#
langsupport --default=en_US
#
#System keyboard
#
keyboard us
#
#System mouse
#
mouse genericwheelusb
#
#Retrieve rescue system from NFS
#
nfs --server=10.20.2.3 --dir=/var/kickstart/RHEL/4/ES/r1
#
#Network information
#
network --bootproto=dhcp
