  1. An all-black LAMY Safari fountain pen filled with a mix of water, Platinum carbon black, and inkjet printer ink.
  2. A blank sheet of A4, folded in half three times.
  3. My passport.
  4. A fully loaded Secrid card carrier.
  5. A really nice rock. It has been in my pocket for a year. Don't think about it.
  6. A dumb watch. (Casio W-59. Very small, light as a feather. Green LED-backlight LCD display. 50 metre water resist. Tough, within reason. Effectively infinite battery life.)
  7. A beta of the PinePhone Pro, equipped with dreemurrs archlinux.
  8. A USB drive containing all of my computers' boot partitions and Archiso.

Why this specific formula for the fountain ink? Beautiful pen, by the way.

What do you use to manage the ISOs? Or did I misunderstand #7?

There is one ISO and three boot partitions.

First of all, I formatted the USB drive with one vfat partition. Then I copied the contents of the ISO over. That and some prodding in grub.conf is enough to get the ISO working, and there is a whole lot of extra space in the vfat partition.

The entire contents of all of my computers' hard drives is encrypted, but that leaves the boot partition. So I moved the boot partitions onto the vfat partition, each in a separate folder labelled by the host. Then, I added entries to grub.conf for each host. The USB drive boots and a boot menu appears with all of the ISO's entries, plus a list of hosts. I choose the right host, then boot.

(I need the USB drive mounted before I can update the kernel or the microcode.)

Essentially a yubi key for simple terms, yes?

[–] etuomaala@sopuli.xyz 2 points 9 months ago (1 children)

IDK, do people use yubi keys to do LUKS?

[–] SendMePhotos@lemmy.world 2 points 9 months ago (1 children)

Idk what lukz is. I'm just trying to simplify it so I understand

[–] etuomaala@sopuli.xyz 2 points 9 months ago

LUKS is full hard drive encryption. If you encrypt your entire hard drive with a yubi key, then lose the yubi key, and you have no backup, you're shit outta luck. I encrypted my hard drives with a USB drive in a similar fashion. Then made backups of the USB drive, so that the scenario I describe wouldn't happen. Hopefully. It's kind of like horcruxes. If somebody steals them all, I become mortal again. Actually, though, if somebody steals them all, I lose all of the data on the hard drive.
