I realize that this is an important feature to preserve the hardware, but I still find it rather draconian, and suboptimal from a UI perspective. Could we change it to be: after N seconds: go to single user. after N + M seconds: shutdown. This would normally allow X11 to shut down cleanly, which again means we can printf a message to the user about what is happening instead of simply going black screen on them. It would also save people some fsck'ing subsequently. I realize there is a rainbow of bikeshed proposals about not scheduling non-root/userland/cpu-hog processes etc etc etc. Apart from the fact that it is merely sugarcoating the broccoli, we are not geared for that scheduler-wise and we should not add features to our schedulers until the current issues with them have been solved and settled. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 phk@FreeBSD.ORG | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence.
