I have upgraded my personal laptop to #Fedora#Silverblue just in time for the upgrade to Fedora 40 to be an update in the background and then a trivial, quick reboot into the upgraded system with an option to roll back if something goes wrong.
I started this update in December, by starting with a new (larger) drive. I put it into a USB-3 NVME carrier, attached it to a VM, and did an install and updates until it looked like I got the software I wanted complete.
Then an unrelated hardware failure made me back-burner it until tonight. I booted the VM, did a quick rpm-ostree upgrade, and rebooted the VM into the latest release. Four months of updates and it was fast and trivial. Copied my home directory over from the old drive to the new drive, popped it in, and I'm up and running.
I'm really looking forward to not watching minutes of updates scroll by with the system unusable at the boot screen.
And if I need any files from the old install, I have the old drive in the USB-3 NVME carrier. ☺
