Trying to layer a proprietary RPM fails on dbus errors

Hello,
I’m trying to install software for my USB oscilloscope. Since the installer makes changes in firewall and USB udev rules, I figured it would be better to layer it.

rom-ostree is failing and throwing this in the logs:

-- Boot 04308278b77c488aa45d161db8c18bf5 --
Jul 04 18:56:28 flint rpm-ostree(digilent.adept.runtime.post)[5088]: Failed to send reload request: No such file or directory
Jul 04 18:56:31 flint rpm-ostree(digilent.adept.runtime.post)[5148]: Error: DBUS_ERROR: Failed to connect to socket /run/dbus/system_bus_socket: No such file or directory
Jul 04 18:56:31 flint rpm-ostree(digilent.adept.runtime.post)[5180]: Error: DBUS_ERROR: Failed to connect to socket /run/dbus/system_bus_socket: No such file or directory

A quick look reveals that the socket file is in fact present.

Can I do anything to fix this? Is there a way to use software with mandatory USB access out of toolbox? Do I have to switch to a mutable distro?

You can use rpmbuild - how to extract the instructions provided by the rpm spec file - Unix & Linux Stack Exchange to dump the post scripts from an RPM file and look at what they are doing:

$ rpm -qp --scripts foo.rpm > scripts

Another option is to mount a writable overlay on top of /usr and install the RPM:

$ sudo rpm-ostree usroverlay
$ rpm -Uvh foo.rpm

This will be cleaned-up on reboot but that should “make things work” in the meantime.

Added dbus

I’m trying to install the same software (Digilent Adept Runtime to support Digilent Waveforms), and here is the postinstall script: Fedora · GitHub

It’s not at all clear to me what’s causing the error (though I’m not an expert on rpm-ostree). When I edit the file to remove the postinstall stuff, I can even run the script successfully.

From a quick look, the udevadm & firewallcmd command will fail, as this is not a running system.

Makes sense. Is there any way to have it skip those commands? I guess I could temporarily replace the binaries with stubs lol

Another idea: is it possible for Digilent to have their RPM skip those commands when being used in an rpm-ostree context?
