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.

Anyone ever have cryptsetup just start hanging after entering password on boot? This seems like it's going to be a fun issue to try to resolve...

how about systemd-analyze and cryptsetup luksDump <lukspart> | grep Slot

[–] wesker@lemmy.sdf.org 1 points 6 months ago

I'm not using systemd. Grepping on Slot doesn't return any results.
