How to create a persistent live USB?

Goal: have a pocket system you can carry around.

I have had really bad experiences with traditional dnf Fedora, so that I would want to use Fedora Atomic on a live USB.

One deployment has about 7GB of size, so even though you have BTRFS deduplication, I would say

  • 1GB boot
  • 7+6GB system
  • 10GB home

At least 25GB of storage are needed.

In general I assume Debian or Enterprise Linux would be way better suited for this, as the versions are stable, and the USB key is used on demand and not regularly updated.

A hack to make installers allow installing on a USB stick was to create a GPT partition table on it. But this may not work on Anaconda.

This should work for a USB dongle SSD or NVME drive.
Flash drives would be slow and subject to unexpected failure with the much shorter life they have by default.

If it requires installation, will it still be hardware-agnostic, or will it get configured upon the system used at install time?

Am I wrong in thinking that you meant you would want to use Fedora Atomic?

I have seen some really nice and small NVMe enclosures, even with keychain attached to them.
