TUMBLEWEED Ordering cycle at boot with nss-lookup: named fails to start initially; workaround: manually `rcnamed start`

Posted by jpluimers on 2021/01/15

I have seen this on one Raspberry Pi 3 system: named failing to start during a normal reboot.

The solution is to manually rcnamed start as root after boot.

From [Wayback] TUMBLEWEED Ordering cycle at boot with nss-lookup, the rcnamed status is the same as on my system, but no solution in that thread:

# systemctl status named
● named.service - Berkeley Internet Name Domain (DNS)
     Loaded: loaded (/usr/lib/systemd/system/named.service; enabled; vendor preset: disabled)
     Active: inactive (dead) Jul 02 08:13:40 hpprol2 systemd[1]: nss-lookup.target: Found ordering cycle on named.service/start
Jul 02 08:13:40 hpprol2 systemd[1]: nss-lookup.target: Found dependency on time-sync.target/start
Jul 02 08:13:40 hpprol2 systemd[1]: nss-lookup.target: Found dependency on ntpd.service/start
Jul 02 08:13:40 hpprol2 systemd[1]: nss-lookup.target: Found dependency on nss-lookup.target/start
Jul 02 08:13:40 hpprol2 systemd[1]: nss-lookup.target: Job named.service/start deleted to break ordering cycle starting with nss-lookup.target/start

Apparently, sometimes there is a service startup dependency loop, and named becomes the victim of it, effectively rendering DNS inoperable.

My system was running this version of Tumbleweed:

statler:~ # cat /etc/SUSE-brand /etc/os-release 
openSUSE
VERSION = tumbleweed
NAME="openSUSE Tumbleweed"
# VERSION="20200825"
ID="opensuse-tumbleweed"
ID_LIKE="opensuse suse"
VERSION_ID="20200825"
PRETTY_NAME="openSUSE Tumbleweed"
ANSI_COLOR="0;32"
CPE_NAME="cpe:/o:opensuse:tumbleweed:20200825"
BUG_REPORT_URL="https://bugs.opensuse.org"
HOME_URL="https://www.opensuse.org/"
LOGO="distributor-logo"

On an identical system, the boot just worked fine, so it might be timing related.

waldorf:~ # cat /etc/SUSE-brand /etc/os-release 
openSUSE
VERSION = tumbleweed
NAME="openSUSE Tumbleweed"
# VERSION="20200825"
ID="opensuse-tumbleweed"
ID_LIKE="opensuse suse"
VERSION_ID="20200825"
PRETTY_NAME="openSUSE Tumbleweed"
ANSI_COLOR="0;32"
CPE_NAME="cpe:/o:opensuse:tumbleweed:20200825"
BUG_REPORT_URL="https://bugs.opensuse.org"
HOME_URL="https://www.opensuse.org/"
LOGO="distributor-logo"

It has been fixed late January 2021 as per [Wayback] Bug 1177491 – systemd ordering cycle with nss-lookup.target:

Fixed by removing "Before=nss-lookup.target" from systemd's service file.

Having the Tom Bihn Brain Bag as day-to-day backpack, I wonder about the PeakDesign Travel Backpack

Posted by jpluimers on 2021/01/15

Having the Tom Bihn Brain Bag as day-to-day backpack, I wonder about the PeakDesign Travel Backpack.

The features I like most about the [WayBack] Tom Bihn Brain Bag are:

  • that it has 2 big main compartments,
  • the rail system allowing easy attached removal of one or two laptop caches [WayBack],
  • the freudian slip insert [WayBack],
  • the snake charmer accessory [WayBack],
  • the materials last forever
    (my first lasted 20+ years, so I gave it to mentally retarded brother. To bad he disposed it, not realising how durable it was “it was too big for my work-stuffand too small for my diving flippers, so I threw it away”)

Two more things I like, but are not available any more (new products are being designed for them):

I wonder about the material differences between the two too backpacks.

Here are some links if you want to compare them yourself:
