Re: Two installer bugs
Apparently, the system maintenance was able to swap the files and symlinks without causing a crash. Perhaps permitting the operation if and only if the prior version is the same as the current driver would be a better option?
It's undesirable to terminate X, because that also means terminating any running applications and open documents. Since no one is present at the time maintenance is performed, there's no way to determine the impact to the end user of forcing X to close down.
