On some systems, after upgrading OpenSuSE Tumbleweed to 20160905 ntp stops working.
Pending the verification of snapshot 20160908 (not finished yet), if if you have updated to 20160905 or 20160907,, the bogus ntp version is, so you have to downgrade:
zypper in --oldpackage http://download.opensuse.org/tumbleweed/repo/oss/suse/x86_64/ntp-4.2.8p8-1.3.x86_64.rpm systemctl restart ntpd.service
Or wait a few hours and install snapshot 20160908.

I figured this out, it turned out to be a DNS resolution issue. For some reason leaving ‘search localdomain’ in resolv.conf generates some slowness. I’m not sure if it’s because 127.0.0.1 isn’t mapped to ‘localhost.localdomain’ in /etc/hosts by default, or whatever, but taking it out fixes the performance issue.

This succeeded: https://openqa.opensuse.org/tests/overview?distri=opensuse&version=Tumbleweed&build=20160901&groupid=1 installing the image from http://download.opensuse.org/tumbleweed/iso/openSUSE-Tumbleweed-DVD-x86_64-Current.iso.mirrorlist (for which the md5 and sha signatures match).
But I got this cd:/content: Invalid signature. Installation aborted. message:
After a few statements [WayBack] in the install shell:
mkdir /mnt/cd
mount /dev/cdrom /mnt/cd
cd /mnt/cd

Indeed the cd:/content didn’t verify as content.key wasn’t a trusted signature:

One thing I’ve not figured out yet is this: How does enabling btrfs quotas impact the system? – Unix & Linux Stack Exchange
My gut feeling says it’s not much. But if someone knows: please chime in.
Anyway: btrfs quota support helps you to see how big snapshots (and other subvolumes) are.
Enabling and disabling is easy (the slash is the path from where to enable quota):
btrfs quota enable /
btrfs quota disable /
The bad thing is that there is no command that gives just the quota status. You have to revert to btrfs qgroup show /
This will show you quota groups when quota are enabled:
qgroupid rfer excl -------- ---- ---- 0/5 16.00KiB 16.00KiB
or errors when quota are disabled either of these two errors:
# btrfs qgroup show / ERROR: can't perform the search - No such file or directory ERROR: can't list qgroups: No such file or directory # btrfs qgroup show / ERROR: can't list qgroups: quotas not enabled
You might also want to check the syslogs as there was a [PATCH 1/2] btrfs: syslog when quota is enabled.
The btrfs qgroup output is the base for agronick/btrfs-size: A script that will print out a list of BTRFS subvolumes along with their size in megabytes and their name.
It actually shows it in human readable form (kilo/mega/giga/… bytes) and is documented at Get the size of your BTRFS Snapshots | PoisonPacket. It gives me a nice overview that corresponds to the snapper list output (see below).
The script has two drawbacks:
./btrfs-size/btrfs-size.sh: line 55: can't + 0: syntax error: invalid arithmetic operator (error token is "'t + 0")
btrfs quota enable / to actually deliver the quota for all the qgroupid values snapper uses. Until that time, the columns ID/Total/Exclusive Data are empty.
# btrfs qgroup show / > /dev/null
WARNING: Qgroup data inconsistent, rescan recommended
In that case, run btrfs quota rescan / and wait for it to complete by running this command until the warning is gone:
# btrfs qgroup show / > /dev/null
WARNING: Rescan is running, qgroup data may be incorrect
If the warning reverts to WARNING: Qgroup data inconsistent, rescan recommended then you might see the effects from this bug and should not worry about it: Bug 933428 – btrfs qgroup – allways shows WARNING: Qgroup data inconsistent.
For more btrfs quota background information, see: UseCases – btrfs Wiki.

TL;DR: I’m not the only one being partially word-blind.
I had the below while performing a zypper distribution upgrade on "openSUSE Tumbleweed (20160726) (x86_64)".
revue:/etc # zypper dist-upgrade
...
Detected 2 file conflicts:
File /usr/bin/mt
from install of
mt-st-1.3-1.1.x86_64 (Main Repository (OSS))
conflicts with file from package
mt_st-1.3-1.2.x86_64 (@System)
File /usr/sbin/stinit
from install of
mt-st-1.3-1.1.x86_64 (Main Repository (OSS))
conflicts with file from package
mt_st-1.3-1.2.x86_64 (@System)
File conflicts happen when two packages attempt to install files with the same name but different contents. If you continue, conflicting files will be replaced losing the previous content.
Continue? [yes/no] (no): no
Problem occured during or after installation or removal of packages:
Installation aborted by user
Please see the above error message for a hint.
Did you see the cause of the error in the above message?
Neither did I.
So I went to the #opensuse-factory IRC channel on freenode with this information:
revue:/etc # zypper repos --details # | Alias | Name | Enabled | GPG Check | Refresh | Priority | Type | URI | Service --+-------------------------------------+----------------------------+---------+-----------+---------+----------+--------+----------------------------------------------------------------------------------------+-------- 1 | download.opensuse.org-non-oss | Main Repository (NON-OSS) | Yes | (r ) Yes | Yes | 99 | yast2 | http://download.opensuse.org/tumbleweed/repo/non-oss/ | 2 | download.opensuse.org-oss | Main Repository (OSS) | Yes | (r ) Yes | Yes | 99 | yast2 | http://download.opensuse.org/tumbleweed/repo/oss/ | 3 | download.opensuse.org-tumbleweed | Main Update Repository | Yes | (r ) Yes | Yes | 99 | rpm-md | http://download.opensuse.org/update/tumbleweed/ | 4 | http-download.opensuse.org-f3ba78e8 | server:monitoring | Yes | (r ) Yes | Yes | 99 | rpm-md | http://download.opensuse.org/repositories/server:/monitoring/openSUSE_Tumbleweed/ | 5 | openSUSE-20150508-0 | openSUSE-20150508-0 | No | ---- | No | 99 | yast2 | cd:///?devices=/dev/disk/by-id/ata-VMware_Virtual_IDE_CDROM_Drive_10000000000000000001 | 6 | repo-debug | openSUSE-Tumbleweed-Debug | No | ---- | Yes | 99 | NONE | http://download.opensuse.org/debug/tumbleweed/repo/oss/ | 7 | repo-source | openSUSE-Tumbleweed-Source | No | ---- | Yes | 99 | NONE | http://download.opensuse.org/source/tumbleweed/repo/oss/ | revue:/etc # cat /etc/os-release NAME=openSUSE VERSION="Tumbleweed" VERSION_ID="20160726" PRETTY_NAME="openSUSE Tumbleweed (20160726) (x86_64)" ID=opensuse ANSI_COLOR="0;32" CPE_NAME="cpe:/o:opensuse:opensuse:20160726" BUG_REPORT_URL="https://bugs.opensuse.org" HOME_URL="https://www.opensuse.org/" ID_LIKE="suse"
There cooloo pointed out both the cause and solution were deceptively simple:
coolo: wiert: zypper remove mt_st ; zypper dup; zypper in mt-st
coolo: the package was incorrectly renamed
My partial word-blindness didn’t spot the difference between mt_st and mt-st, but it was indeed renamed.
So here I went:
zypper remove mt_st ; zypper dist-upgrade; zypper install mt-st
Note that strictly zypper install mt-st isn’t needed on my system as it is part of Base:System. which means that zypper dist-upgrade automatically re-installed it.

Kev:
Try the command line tool expand.
expand -t 4 input >output
And for those systems that don’t use the GNU Core Utilities, you have a decent chance of expand being installed since it is standardized by The Open Group’s Single Unix Specification. See Issue 6, which is from 2001, though some updates were applied, hence the year of publication being 2004: expand

One day I’m going to need this: Make A Bootable Windows 10 USB Install Stick On Linux With WinUSB Fork ~ Web Upd8: Ubuntu / Linux blog
So I’m glad WinUSB (which hadn’t been maintained for a long time) got forked on github by slaka.
Since my day-to-day unix-like system is OS X, I’d love a good working solution there too which means I probably need to investigate a bit along these lines:

sponge, a great *nix tool part of moreutils:
sponge: soak up standard input and write to a file
Now need to figure out how to get it on Tumbleweed; maybe http://rpm.pbone.net/index.php3/stat/4/idpl/23781842/dir/opensuse/com/moreutils-0.48-1.1.i586.rpm.html
