Hi,
for one of my computer, I need to add some files in /usr/share/alsa/ucm in order to have a working sound. I’d like to switch it to Fedora Silverblue but I can’t figure if doing this is possible without creating a RPM, which seems to be the only way to make changes to the base system through rpm-ostree from my searches.
Could someone confirm me that making a RPM is the only way?
Vanilla OS or MicroOS immutable management allows to open a shell to make change to the future system, which is quite handy for these changes, but ostree doesn’t seem to have a similar feature, I suppose it’s because it would be complicated to layer
