From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

For me it is not recording credentials with the assumption I would simply remember them later, while having every opportunity to archive them before eventually forgetting. Also, not keeping detailed enough notes & photos of exactly how my hardware is attached.

dd if=fedora.iso of=my ssd instead of flash drive :’(

Now you know why it’s called the Disk Destroyer.

Before using dd, I prefer to run lsblk first so that I can see what each disk is called. Before pressing enter, I also double check the names with the lsblk output.

TIL about using lsblk instead of just reading through the output of journalctl to find the disk and partitions. Thanks!

Glad I could help! This command is just so much nicer.

Always triple check dd

i love the raspberry pi imager for that reason. i don’t want no balena etcher stealing my data, but a gui is very convenient for flashing isos, so raspi imager it is! (works for any iso you want)
