Goal: keep Whonix-Host ISO kernel boot parameters synchronized with Whonix-Host Installed with no manual code changes requires as kernel boot parameters change.
In both cases…
(isolinux -> chainload grub?)
Could we embed /boot/grub/grub.cfg to keep kernel boot parameters of Whonix-Host in ISO mode in sync with Whonix-Host Installed?
What I mean by embed:
- grub supports a feature similar to bash’s
sourcecommand - (Or
sh's.command). - https://www.gnu.org/software/grub/manual/grub/grub.html#Embedded-configuration
-
https://www.gnu.org/software/grub/manual/grub/grub.html#configfile
-
Command: configfile file
-
Load file as a configuration file. If file defines any menu entries, then show a menu containing them immediately. Any environment variable changes made by the commands in file will not be preserved after configfile returns.

https://www.gnu.org/software/grub/manual/grub/grub.html#index-source
-
Command: source file
-
Read file as a configuration file, as if its contents had been incorporated directly into the sourcing file. Unlike configfile (see configfile), this executes the contents of file without changing context: any environment variable changes made by the commands in file will be preserved after source returns, and the menu will not be shown immediately.

Ideally grub.cfg runs “source /boot/grub/grub.cfg”.
isolinux.cfg -> chainboots grub -> “source /boot/grub/grub.cfg”…
“source /boot/grub/grub.cfg” might not work as if. Might need to define device somehow.
