Using a helper script
zipl provides a helper script, zipl_helper.device-mapper,
that detects the required information and provides it to zipl for
you.
The helper script is used automatically when you run zipl to prepare a boot device. Specify the parameters for the kernel image, parameter file, initial RAM disk, and target as usual.
Assuming an example device
for which the location of the kernel image is /boot/image-5,
the location of an initial RAM disk as /boot/initrd-5,
a kernel parameter file /boot/parmf-5, and which
writes the required boot loader code to /boot and
is a device mapper device, the command then becomes:
# zipl -i /boot/image-5 -r /boot/initrd-5 -p /boot/parmf-5 -t /bootThe
corresponding configuration file section becomes:
[boot5]
image=/boot/image-5
ramdisk=/boot/initrd-5
paramfile=/boot/parmf-5
target=/boot
