recently my system (Fedora workstation 34) during boot , boot messages changed, also what appears to be the same code executes at shutdown as well. what specifically is the system doing here? how do I determine what the hex code is executing? or is this normal and I an idiot. output for dmesg:

PackageKit provides a common interface to various update software, in your case dnf. The error suggests there is a bug in either packagekitd or libdnf.so. I suppose the code is what it was executing at the time, but it doesn't seem to be particularly helpful, does it? error 7 usually means "Argument list too long", which might be some kind of clue. Current on my Fedora 34 system is:

"radeon" has something to do with AMD graphics. "drm" too, indirectly.
"systemd-sysv-generator" clearly tells you what the matter is - it's more of a notice/warning anyhow.

Not so familiar with SELinux.

Nothing here looks worrisome to me.

The warnings about livesys are unrelated to PackageKit. Those are leftovers caused by installing from live media.
