After the reboot, I decided to install the flashrom package, and after the install finishes, I find in front of me what appears to be an execute-command-as dialog.
No command. User selection popup list showing root.
I assume it's the execute-as dialog, but I don't recall doing anything to get the dialog, so it's strange to see it. (Maybe my fingers moving by themselves when I find I can't stay awake?)
Probably not important, but if others are seeing such a dialog when they don't expect it, I'd like to hear about it.
