[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)
