Currently the 92-tuned.install kernel-install plugin adds the tuned params to the BLS config files in s390x machines. But the zipl bootloader doesn't have support for variables, which leads to cmdlines like the following: root=/dev/mapper/rhel-root crashkernel=auto rd.dasd=0.0.541f rd.dasd=0.0.551f rd.dasd=0.0.561f rd.dasd=0.0.571f rd.lvm.lv=rhel/root rd.lvm.lv=rhel/swap cio_ignore=all,!condev rd.znet=qeth,0.0.0600,0.0.0601,0.0.0602,layer2=1,portno=0 $tuned_params BOOT_IMAGE=0 Don't modify the BLS snippet since the zipl bootloader doesn't support the variables and just make the script to exit if the architecture is s390x.
