Description of problem:

Starting on Satellite 6.12.2 (foreman-3.3.0.20-1.el8sat.noarch) a new version of the snippet kickstart_kernel_options is shipped.

This new version includes new options that push a parameter "static=1" to the ks URL. However, when pushing this extra parameter, it needs to co-exist with token=<token> on the same URL. The URL generated is not properly escaped and then we hit this Grub2 issue¹

Solution is to properly escape the URL.
