I am updating grub parameters in RHEL 7.0 with grubby command using
/usr/sbin/grubby --update-kernel=ALL --args='isolcpus=14-24'
followed by /usr/sbin/grub2-install /dev/sda and reboot
I very well understand the process to manually configure and validate boot parameters. I simply have to edit/check /etc/default/grub file and add/validate boot parameters in GRUB_CMDLINE_LINUX variable.
My question is: Can grubby or any other tool validate if a boot parameter is added. I am trying to avoid manual reads to grub file and string operations. E.g. in above example a command (or tool) should validate if isolcpus parameter is properly added to grub.
I have read grubby manual here but couldn't figure out any relevant flag.
