Shows where the currently detected Linux boot entries get their kernel command-line options.

Generated menu entries usually come from the GRUB defaults file when the menu is regenerated. BLS entries may instead store options in /boot/loader/entries files, or reference $kernelopts.

kernelopts is not a setting in /etc/default/grub. It is a GRUB environment value stored in grubenv and commonly managed with grubby. Webmin does not edit grubenv directly; when grubby is available, Webmin asks it to apply changed kernel options to existing BLS entries.
