But IF you mess up (because you did not read the instructions carefully enough) you have TWO kernels to reboot, undo your changes and reboot a second time (like others mentioned before) being at the old level. Normally with a -RELEASE (that is what you are using) you can compile and stress test your hardware all day with different kernels - and they will work. > > But it is safe to say that you are a beginner with FreeBSD, no ? > > > > > Have you recompiled your kernel yet? > > > > Yes, I recompiled it this afternoon in order to disable Ctrl-Alt-Del. > > Were you scared ? > Recompiling the kernel is really nothing to be worried about. > I honestly don't see it a bigger problem than installing a port. > > > > Do you know _why_ most of the FreeBSD people > > > use customized kernels? > > > > Because much of what they want to do apparently cannot be enabled by simple > > configuration switches at run-time (such as the change I desired above). > > Like installing hardware ? > > If there's a way to disable ctrl-alt-delete with recompiling the kernel, > then you'd probably find that there was a way to turn it back on... > > > > Why do you speak up about a topic in an OS you > > > don't know much about? > > > > I know quite a bit about operating systems. > > But you don't know all that much about FreeBSD, which was the question. I would go one step further: You have experience with Multics as you told us and with a bundle of Microsoft Windows versions. What else? Ever used another Unix flavor before? No? But you know about the things behind. (I for my part has used Novell since 2.1, SCO Unixware, Solaris, HP-UX, AIX, IRIX, NT since 3.51, VMS, OS/2 since 2.x, Linux, FreeBSD, working on a S/390. All systems were production systems for small or bigger companies with me as administrator.) I say I know nearly nothing about operating systems. I have never build one myself. Haven't been full there is the same as being not there. > > > > _Where_ is the problem? > > > > You know it when you see it, usually when you have to jump out of bed and rush > > down to the computer center at 3 AM.

(One time it was a Linux kernel crashing saturday morning, because i left the machine fresh compiled and with now new config some hours before to go to a party, changed config, gone to bed, slept well. Can do it again, party was good. The other times done a reinstall of Windows NT. More then once. Not slept well. No desire to do it again.) > > If you recompile kernels from your bed then yes, you are probably asking > for trouble.

I will be quite again and answer only to technical stuff again. Don't feed .... Marc __________________________________________________________________ Gesendet von Yahoo!
