[arch-general] Think twice before moving to systemd
by Felipe Contreras 26 Aug '12

26 Aug '12

Hi, I just became aware that Arch Linux plans to switch to systemd, and this worries me for several reasons. I tried systemd a while ago in a brand new machine with Arch Linux and the boot was *much slower*. After some exchanges with Lennart Poettering and other people in Google+[1], it became clear I was on my own. Eventually I found the culprit: Fedora uses CONFIG_HZ_1000, and Arch Linux uses CONFIG_HZ_300. It became clear to me that systemd was not ready for prime time, it wasn't thoroughly tested in a lot of machines, and if you have problems Lennart Poettering will blame you (PulseAudio sounds familiar?). systemd was the reason I stopped using Fedora in the first place; when they moved to it my machine stopped booting reliably. My configuration was non-standard (a single encrypted partition), so I guess they never tested that. Similarly, I expect many Arch Linux users to bite these corner-cases. Finally, it's much harder to debug. If you have a problem you will not be able to open a script and figure out what is happening, and perhaps modify it, and debug it. You would be greeted with an unmodified binary, and the source code would be along these lines: http://cgit.freedesktop.org/systemd/systemd/tree/src/remount-fs/remount-fs.c I'm sure in due time systemd will be ready, and will have nice advantages, but I doubt that's the case right now. Has anybody looked into the CONFIG_HZ issue? I doubt that. I was expecting more from the Arch Linux community, something along the lines of Google's analysis to pick to mercurial[2], but so far I have only seen a couple of people saying +1 in the development mailing list, with barely any explanation at all. Such an important move (one that might make users' machines stop booting) should warrant at least an analysis of some sort, with clear advantages. Would it not? At the moment I am unconvinced; does systemd has any *real* advantage? I don't think so; the potential of breakage outweighs the "supposed" advantages, and I think a proper analysis would show that. Cheers. [1] https://plus.google.com/108736516888538655285/posts/BTG39o6YoGS [2] http://code.google.com/p/support/wiki/DVCSAnalysis -- Felipe Contreras

[arch-general] /etc/dbus-1/systemd/cups.conf and /usr/lib/systemd/system/cups.socket files
by Myra Nelson 26 Aug '12

26 Aug '12

After my research on sysvinit, the simple version, I'm working my way through systemd. Two things I noticed about the cups configuration: 1: The cups.conf file in /etc/dbus-1/systemd reads <!DOCTYPE busconfig PUBLIC "-//freedesktop//DTD D-BUS Bus Configuration 1.0//EN" "http://www.freedesktop.org/standards/dbus/1.0/busconfig.dtd"> <busconfig>  <policy user="root"> <allow send_interface="com.redhat.PrinterSpooler"/> </policy>  <policy context="default"> <allow receive_interface="com.redhat.PrinterSpooler"/> </policy> </busconfig> Do the allow send and allow receive interfaces need to be changed, or is this taken into account by the rest of systemd? 2. The /usr/lib/systemd/system/cups.socket reads [Unit] Description=CUPS Printing Service Sockets [Socket] ListenStream=/var/run/cups/cups.sock ListenStream=631 ListenDatagram=0.0.0.0:631 BindIPv6Only=ipv6-only [Install] WantedBy=sockets.target What is the recommended best practice for dealing with this when you have no access to IPv6? Our satellite console supports IPv4 only so previously everything has been set up on 192.168.???.??. With the newer version of cups depending on avahi and the differences in the avahi hosts file and the hosts file, avahi uses gandalf.local while hosts still uses .localdomain. https://lwn.net/Articles/485617/ I'm not trying to be dense here, but some of this seems to be at cross purposes. That or this is something sysadmins on large systems do all the time and those of us with small installations haven't had to deal with yet. As with some of my other posts, trashing systemd etc and those behind it accomplishes nothing. If you can't say anything constructive, STFU. I apologize for offending anyone, but this would be easier with out all the BS, and I don't mean bikeshed. Myra -- Life's fun when your sick and psychotic!

Hello, Is anyone here using "stapler-git" from the AUR? I'm trying to use it to combine two pdf files into one and it's not working for me. When using the command "stapler cat 1.pdf 2.pdf output.pdf" it just returns the message "error". Could someone try this to see if it works ok? Thanks

[arch-general] systemd native files in etc
by Qadri 24 Aug '12

24 Aug '12

Hi all, Given all the hullabaloo about systemd I thought I'd try it out. I went to the wiki and saw that it has listed several "native systemd configuration files" that it looks for, and if they're absent, it takes info from rc.conf. It's "strongly advised" (by the wiki) to use the native files. Is there a package that provides these /etc files, like hostname, vconsole.conf, locale.conf? It feels weird creating untracked files in /etc. Is there interest in an aur package (e.g. systemd_etc_files) that I could make with all the many comments and options that are essentially in the rc.conf (or other files)? What package will eventually provide these? MAQ.

is there any free secondary dns provider that supports zone transfer? BTW: well, this is kind of off topic as it hasn't to do with arch, but help is needed... :P thanks in advance! -- (\_ /) copy the bunny to your profile (0.o ) to help him achieve world domination.

[arch-general] lib -> usr/lib move, glibc and curl
by Christian Hesse 23 Aug '12

23 Aug '12

Hello everybody, I just updated an old system and had to go through the lib -> usr/lib move. I did an pacman -Syud --ignore glibc and ended in a broken package manager. pacman is linked against libcurl, which is compiled against glibc 2.16.0 and includes versioned symbols. Luckily I had an old curl package around to temporarily fix the problem and update the system. Others may be out of luck, so... Do you think this needs some more investigation? -- main(a){char*c=/* Schoene Gruesse */"B?IJj;MEH" "CX:;",b;for(a/* Chris get my mail address: */=0;b=c[a++];) putchar(b-1/(/* gcc -o sig sig.c && ./sig */b/42*2-3)*42);}

[arch-general] Cannot chainload arch core.img from legacy GRUB installed in MBR.
by Juan R. de Silva 23 Aug '12

23 Aug '12

While installing and configuring grub-bios files for my new Arch installation I followed GRUB2 wiki article. In the section "Install grub-bios boot files" I opted to the option "Generate core.img alone" to "generate a /boot/grub/i386-pc/core.img file without embedding any grub-bios bootsector code in the MBR, post-MBR region, or the partition bootsector". At this point GRUB2 article says:"You can then chainload GRUB2's core.img from GRUB Legacy or syslinux as a Linux kernel or a multiboot kernel." I also generated grub.cfg file as per GNOME2 wiki, though it was not totally clear to me why this step was required for "Generate core.img alone" option. To chainload my new installation I entered the following lines in menu.lst of my Legacy GRUB installed in MBR: title Arch Linux 2012.8.04 (/dev/sda3) root (hd0,2) kernel /boot/grub/i386-pc/core.img While trying to chainload Arch my Legacy GRUB just hangs up displaying the last line without error messages. Am I missing something, or the installation instructions are erroneous? Could somebody help me, please? Thanks.
