Is this somehow reflected in the dependencies? And how could I deal with the multiple versions of util-linux that seem to be required? Perhaps I should forcefully update util-linux and use tty-helpers so that apcupsd still works in case I reboot. But what other problems might that cause? What am I supposed to think? Should we not update unless no problems are listed and just wait in case there are some, potentially having to wait indefinitely?

I should warn you against including all of those -mno-xxx flags. This has been known to break the build process for packages like chromium, which always wants to build with SSE4 support and toggles it off at runtime. Passing -mno-sse4.1 causes a build failure as it tries to use macros that are not defined. Isn't it possible that removing it for all packages would cause a more subtle problem with another faulty ebuild (like a program crashing due to an illegal instruction)? Passing -march=atom should be sufficient to ensure that you don't get any illegal instructions. The -mno-XXX flags are redundant, and MOSTLY harmless. In the case of chromium, the build system adds -msse4.1 for specific files (just the ones using SSE4.1 instructons). When you have -mno-sse4.1, this takes precedence and the build fails.

Portage wants to upgrade you to the latest version of sysvinit, but you don't have a new-enough util-linux installed with USE=tty-helpers, and you didn't tell portage it was allowed to set that flag, so it doesn't know what you want to do about the issue. The easiest solution is probably to add sys-apps/util-linux tty-helpers to your /etc/portage/package.use. There appear to be packages requiring various particular versions of util-linux, like 2.20 and 2.16, and there's no more recent apcupsd available, so at least version 2.23 is required. Something similar seems to be going on for sysvinit with openrc and apcupsd requiring different versions of it. -- Again we must be afraid of speaking of daemons for fear that daemons might swallow us.

The thinking is that you can unplug the machine, or press the hardware reset or power button, or flip the PSU switch... Preventing a ctrl+alt+del reboot does not add anything to security. Security doesn't really apply to users with physical access to the machine. Indeed, as witness many successful hijacks of supposedly secure systems. However, this is just a default. You can easily disable reboot on ctrl+alt+del by editing /etc/inittab and commenting-out this line: ca:12345:ctrlaltdel:/sbin/shutdown -r now All good sense. Note though, that is someone wants to reboot, and ctrl+alt+del doesn't work, pressing the reset button is far worse, since there's no clean shutdown performed (unmounting filesystems after flushing caches, etc.) Because of that, the default of allowing ctrl+alt+del for local users makes more sense than disabling it. And there's no arguing with that! :_) -- Rgds Peter.

Re: [gentoo-user] Mutt emerge USE flags for novice
Interesting. When I used IMAP in Mutt, rather than offlineimap, I was really frustrated by the constant lag within Mutt from syncing with the server. Offlineimap isn't the fastest ever at syncing either, but at least it happens all in one go, and then the full contents of all the emails I care about are on my local machine.

I should warn you against including all of those -mno-xxx flags. This has been known to break the build process for packages like chromium, which always wants to build with SSE4 support and toggles it off at runtime. Passing -mno-sse4.1 causes a build failure as it tries to use macros that are not defined. Isn't it possible that removing it for all packages would cause a more subtle problem with another faulty ebuild (like a program crashing due to an illegal instruction)? Passing -march=atom should be sufficient to ensure that you don't get any illegal instructions. The -mno-XXX flags are redundant, and MOSTLY harmless. In the case of chromium, the build system adds -msse4.1 for specific files (just the ones using SSE4.1 instructons). When you have -mno-sse4.1, this takes precedence and the build fails. To put it another way: back in the day before gcc -march=native, nobody would have told you to put a bunch of -mno-xxx flags in your global CFLAGS. They would have told you to find the -march setting most appropriate for your processor.

Re: [gentoo-user] systemd: incorrect behavior when doing poweroff/reboot

When I poweroff or reboot the NFS client machines, systemd tears down the wireless connection *before* it unmounts the /usr/portage share, and so the umount command hangs and the machine won't shut down. I'd think people that hang out in this list must do the same thing, surely? No one else here running into this silly problem? Log a bug. systemd is very new, and if you have a somewhat-unusual configuration (nfs over wifi, for example) it is entirely possible that nobody has noticed a bug like this. I was having issues with an nfs root with dracut+systemd and I found the maintainers of both very interested in bug reports and testing. It seems likely that a dependency is unspecified somewhere. As far as whether the bug is in systemd or dracut, if you have systemd enabled on dracut then dracut will be running systemd anyway, so the config issue will get you either way. -- Rich

It's a defined behavior. I'm with German here. Being designed that way doesn't stop it being strange. I see it as a last resource available for rebooting under any circumstances( Similar to what you can do with Sysrq). Consider: I'm an ordinary user sitting at a terminal. I'm not allowed to halt the machine, but I am allowed to reboot it into perhaps some quite other configuration. Or I can keep rebooting it over and again, effectively preventing the machine from doing its job. How does that make sense? It doesn't and that's why it's configurable, if you are in a high security requiring environment, you disable it.

When you press ctrl-alt-delete kernel recieves it and sends it to the program that has grabbed the keyboard. If this program doesn't trap the sequence it goes to the parent program. Like if you are running a terminal in X it first goes to the shell then terminal and then to X-server. Now usually X traps that and performs what ever action is configured. If you set X not to trap the key press it goes all the way down back to the kernel. When kernel receives it it generates hang-up signal and sends it to the PID 1 aka init. And then executes the command in inittab. ca:12345:ctrlaltdel:/bin/echo shutdown And then: kill -HUP 1 Will print shutdown to your console. If you write a small program that traps ctrl-alt-del and run that in terminal, the server will not reboot :) pressing the reset button is far worse, since there's no clean shutdown, unmounting filesystems after flushing caches, etc. Yes : that's forced only when the keyboard ceases to respond.

Lucky for you and others, Jonathan was aware of the problem and was kind enough to post the solution. This is one of the things that is starting to real get on my damn tits about portage, for about 2 years now. It's not an easy problem to solve, and to be honest, portage is not helping at all. You have two options in running it: don't use -v and get very little info, or use -v and get a terminal dump of the entire graph tree with lots of stuff and zero real information about how to solve it. Look at my thread with Dale just the other day, I managed to help him with the correct answer because I had a magic brainwave to search for the character. Seriously, what kind of process would ever use that as a problem solving approach? In your case, the solution is in the ebuild for acpupsd and it's specific DEPENDs. Now, I'm generally OK with looking in ebuilds for real answers and have gotten used to it, but ffs I should not have to do that.

Some commands were moved from sysvinit to util-linux, and these commands are required by apcupsd and are included in util-linux if it's compiled with the tty-helpers use flag.

Lucky for you and others, Jonathan was aware of the problem and was kind enough to post the solution. This is one of the things that is starting to real get on my damn tits about portage, for about 2 years now. It's not an easy problem to solve, and to be honest, portage is not helping at all. You have two options in running it: don't use -v and get very little info, or use -v and get a terminal dump of the entire graph tree with lots of stuff and zero real information about how to solve it. Look at my thread with Dale just the other day, I managed to help him with the correct answer because I had a magic brainwave to search for the character. Seriously, what kind of process would ever use that as a problem solving approach? In your case, the solution is in the ebuild for acpupsd and it's specific DEPENDs. Now, I'm generally OK with looking in ebuilds for real answers and have gotten used to it, but ffs I should not have to do that. Well-written software should provide that information in it's output, and it shouldn't be hard to get the software to do it. Ok, rant over. +1 and you dang skippy, pat on the back etc etc etc. Dale :-) :-)

As mentioned, the reset button works just fine. You really do want those users to reboot the system properly rather than pressing reset. Environments where the machine is locked away with only the keyboard being accessible are far less common than people sitting in front of the actual machine. We're picturing different set-ups : I'm thinking of a campus system, where the machine is in a locked room accessible to the sysadmin (root) users log in somewhere else via machines which act as terminals ; you are perhaps refering to a family or small-office machine, where there are no other means of access, but users log in separately. You are correct in the latter case. Well, remote logins can't reboot with ctrl+alt+del. That's reserved only for the users using the actual console. Meaning the keyboard hooked up to the machine with the PS/2 or USB cable. SSH login or thin clients can't reboot. If you press ctrl+alt+del on the terminal machine, that's only going to reboot the terminal machine. We had such a setup using Sun Rays in the past. Non-console logins are getting the full security treatment.

You got me curious as to why they're there being redundant and I think I found out why. I looked at the code (gcc/config/i386/driver-i386.c) and there is a very slim chance that the -march reported by gcc when using -march=native will not be the most appropriate. In some cases it's guessed based on the features reported by the CPU but on other cases it trusts the model number and Intel lists several Atom server CPUs and SoCs with no extensions at all (I have no idea what they report themselves like or if their specs are right). All the - mxxx and -mno-xxx flags are determined by the features reported by the CPU so no chance of error there (save from a CPU bug). I guess gcc devs are careful when using the model numbers (Intel lists 3 for Atoms, gcc uses only two so that may account for the models I mentioned) but the chance of error is there. The -mno-xxx flags would safeguard against it. -- Fernando Rodriguez

The main config file is /etc/sudoers *DO NOT TOUCH THAT FILE*. It'll get overwritten every time that an update of sudo comes along. sudo also reads files in its include directory, which defaults to /etc/sudoers.d/ which is where you should put your stuff. You can have multiple files in there, and they will be executed in the same order that they sort. *DO NOT EDIT THESE FILES DIRECTLY WITH NANO/VIM/WHATEVER*. Use the command... visudo -f /etc/sudoers.d/filename where filename is any legal file name. visudo is a sudo feature that * gets your default editor * edits a *WORKING COPY* of the file you want to change * after you exit the editor, it tests the file syntax * if no sudo syntax errors are found it commits the file * if syntax errors are found, it warns you, and allows you to back out I have a single file /etc/sudoers.d/001 but you can have several files if you want.
