[WayBack] Rebooting a Linux server unattended – twm’s blog:
/sbin/shutdown -r now
Simple, but I keep forgetting where Linux has short/long command options and short/long verbs.

On my list of things to figure out: how to force fsck with opensuse Tumbleweed on Raspberry Pi 3
Posted by jpluimers on 2020/09/11
Hopefully the below links will eventually get me further in figuring out how to force fsck with opensuse Tumbleweed on Raspberry Pi 3.
For now, I just reinstalled an SD card (my Mac didn’t support the file systems and I did not have time and equipment with me to mount it to another opensuse based device).
- [WayBack] init – How can I make fsck run non-interactively at boot time? – Ask Ubuntu
- [WayBack] How can I force fsck on next boot on Red Hat Enterprise Linux? (too bad this is behind a content filter)
- [WayBack] 10.04 – Force fsck.ext4 on reboot, but really “forceful” – Ask Ubuntu
- [WayBack] Linux Force fsck on the Next Reboot or Boot Sequence – nixCraft
- [WayBack] Force a full fsck on reboot, ignoring the dirty flag – Raspberry Pi Forums (especially starting at “how I got it to work”)
- [WayBack] GitHub – AlexGhiti/rpi_initramfs_e2fsck
- [WayBack] Force fsck on boot – opensuse

Chromium/Chrome on opensuse Tumbleweed ARM notes
Posted by jpluimers on 2020/07/27
Somehow Firefox is available on ARM by default, but the crash recovery isn’t that awesome.
On my list of things to try is Chrome or Chromium. These links should help me find out if this is possible at all:
- [WayBack] Install package network:chromium / chromium: points to the right repositories.
- [WayBack] Index of /repositories/network:/chromium/openSUSE_Factory/: i586 and x86_64 only (same for [Archive.is] openSUSE Software: Chromium)
- [WayBack] Install package openSUSE:Factory:ARM / chromium: No data for openSUSE:Factory:ARM / chromium
- [WayBack] Chrome Web Browser: has no deep link for “Other Platforms”. The provided choices seem to be x86_64 only: 64 bit .deb (For Debian/Ubuntu) 64 bit .rpm (For Fedora/openSUSE).
- The “community supported” link points to the bug page of Chromium: [WayBack] chromium – An open-source project to help move the web forward. – Monorail
- There is a https://dl.google.com/linux/chrome/rpm/stable/x86_64/repodata/repomd.xml but no https://dl.google.com/linux/chrome/rpm/stable/arm64/repodata/repomd.xml nor https://dl.google.com/linux/chrome/rpm/stable/aarch64/repodata/repomd.xml
- [WayBack] Chromium ARM – EpicChasGamer.com: Debian only.
- [WayBack] chrome – How do I cross-compile Chromium for ARM? – Unix & Linux Stack Exchange: If I need to build for ARM myself.

Eject USB drives / eject command – Unix & Linux Stack Exchange
Posted by jpluimers on 2020/07/20
I always thought than an umount /dev/sdX# for all partitions on /dev/sdX was enough for USB devices to be ejected, but there are three commands that (on most systems) actually power down USB drives (or USB to SD card adapters):
udisks --detach /dev/sdX(requires theudiskspackage which is obsolete)eject /dev/sdXseems not to be enough on some systems; it is part of theutil-linuxpackageudisksctl power-off -b /dev/sdXis equivalent to theudiskscommand; it is part of theudisks2package.
These will ensure that the disk is not part of the fdisk --list output any more.
The opposite of these is sg_start, which is from the sg3_utils package.

On MacOS, you can use diskutil eject /Volumes/<LABEL> (source: answer by efesaid on [WayBack] Eject USB drives / eject command – Unix & Linux Stack Exchange)

openSUSE forums tips
Posted by jpluimers on 2020/07/17
A few tips from posting to the openSUSE forums, learned from banging my head to the wall too often.
- They are at https://forums.opensuse.org/forum.php
- The forum software can be very slow at times taking ~tens of seconds for loading a post:
- loading multiple posts or pages of posts you are interested in multiple tabs speeds up your reading a lot
- Answers on the post often are along the form “has been answered before” without pointing to the actual link, even if the post is marked with a read icon, for instance in [WayBack] No option to “keep me logged in on this device” with Novell/openSUSE login?
- Your email is not your username, so do not use it during logon: [WayBack] Lousy log in
- Be sure to read any forum FAQs, for instance [WayBack] openSUSE Forums FAQ: not logged in
- Logoff can be very soon, not minutes any more, but certainly not 8 hours either: [WayBack] have to login evry few minutes – Page 2
- Keeping a window open to force activity and disable auto-logoff fails in many browser including my Chrome on Mac OS configuration
- There is no auto-logon
- The search function in the forum is horrible.
- Google searching within a subforum fails because of how the forum software is structured: site:forums.opensuse.org/forumdisplay.php/690-How-to-use-the-forums
- This sort of works: site:forums.opensuse.org “How to use the forums?” “logged”
- Google search is always at least few days behind
- The forum software is proprietary (vBulletin – Wikipedia) and has a
- When writing/replying to posts:
- Edit your answer off-line, because
- you will automatically be logged off even if the forum indicates you are still logged on (there is no count down of the activity timer), see
- when you re-logon, your carefully edited text has been lost from the cache
- Never use formatting, either auto-introduced, or introduced while pasting, avoid BB-code
- Reasoning
- The text-based NNTP/e-mail back-end of the forum does not support formatting well
- The HTML editor will without warning interpret all kinds of character combinations
- Those character combinations will be turned into images
- You cannot post too many images at once
- When you re-post, often your post text has been lost from the cache
- The forum editor often gets confused by formatting
- Pasting by keyboard or middle-mouse-button often includes formatting, even: [WayBack/Archive.is] forum: how do get rid of all formatting while pasting? – Page 2
- This happens even when copying from the console: [WayBack] forum: how do get rid of all formatting while pasting?
- Though the forum supports BB code, NNTP news readers do not, and the added formatting gives quite a mess
- If you insist using it: [WayBack] vBulletin.org Forum – BB Code List
- Use the text (“Source mode”) version of the editor, by first clicking the left most button: “Source”
- After this, the third and fourth button get greyed out:
- After this, the third and fourth button get greyed out:
- Remove formatting button is the second from the left (in both text and WYSIWIG mode): “Remove format”
- If you are in WYSIWIG mode, then always paste using the third button from the left that strips formatting: “Paste as plain text”
- NEVER EVER paste with formatting with the fourth button from the left: “Paste from Word”
- Reasoning
- Edit your answer off-line, because
