Description of problem:
Reboot after dnf-system-upgrade gives systemd error 'FreezingExecution'
Version-Release number of selected component (if applicable):
This is on a Thinkpad T430 laptop.
I've seen this error before with 'fedup' a couple of days ago [before it was obseleted by dnf-system-upgrade aswell]. But I was able to reboot back to F22 kernel [and do "fedup --resetbootloader"]
Steps to Reproduce:
1. fedup --network 23
2. dnf system-upgrade reboot
[transcribing message manually from screen]
systemd: [/etc/systemd/system/system-upgrade-shell.service:8] couldn't unescape assignment, ignoring: TERM=linux ps1=system-upgrade:\w\$\x20
systemd: caught <ABRT dumped core as pid200.
Continue of upgrade process.
Current F23 beta snapshot is: 23_Beta_RC1/Workstation
system-upgrade-shell.service only exists in the (now obsolete) upgrade.img that the old fedup uses. So you're still booting the old upgrade boot entry, which we know is broken and useless.
You should delete that boot entry:
new-kernel-pkg --remove fedup
