[Users] adding biosdevname=0 to kernel grub line on ovirt-node persistent
Hi. I'm wondering if it's possible to modify the kernel line (in my case, appending "biosdevname=0") on an installed ovirt-node? Adding it during boot works - I'd just like to know how to make the change persistent. Thanks, Jason.

I'm not sure if this is the "right" way to do it, but I was able to: # mount -o rw,remount /run/initramfs/live # cd /run/initramfs/lib/grub edit grub.cfg and add biosdevname=0 to kernel line Jason.

You can do that and it will work. You can also add entries to the host at installation time and they'll be persisted. I don't believe that this process of editing grub.cfg will persist across upgrades, however. Could you file an RFE to add a method to edit and persist the grub command line? Thanks Mike
Jason.

How would I add the entries to the host at installation time? By adding them to the PXE boot options?

Will do. Jason.
