-### [IM]MUTABLE /opt
-## Some bootable images, like Fedora, have /opt symlinked to /var/opt, in order to
-## make it mutable/writable for users. However, some packages write files to this directory,
-## thus its contents might be wiped out when bootc deploys an image, making it troublesome for
-## some packages. Eg, google-chrome, docker-desktop.
-##
-## Uncomment the following line if one desires to make /opt immutable and be able to be used
-## by the package manager.
