 BerriJ | Do you guys take extra care of versioning disko in your flake or do you just follow master like this?
disko = {
url = "github:nix-community/disko";
inputs.nixpkgs.follows = "nixpkgs";

 Raj | Couple of questions about NixOS live USBs:
I want to partition my 64 GB USB flash drive into two partitions (FAT32 live USB + ext4 storage), so I used the following disko config:
let
usb = "/dev/disk/by-id/usb-USB_SanDisk_3.2Gen1_0401a943ae4197a38a6f9070194e9ea2b3fb8dbb7997e05ed1b197c0e28946be4b8f000000000000000000001cf4be6800926418a955810751ab6336-0:0";
in {
disko.devices = {
disk = {
live = {
type = "disk";
device = usb;
content = {
type = "gpt";
partitions = {
ESP = {
type = "EF00";
device = "${usb}-part1";
priority = 0;
size = "8192M";
content = {
type = "filesystem";
format = "vfat";
};
};
storage = {
device = "${usb}-part2";
priority = 1;
size = "100%";
content = {
type = "filesystem";
format = "ext4";
};
};
};
};
};
};
};
}
I then copied over the files from the (minimal, non-graphical) NixOS live ISO into partition 1, hoping that the instructions on the Arch wiki would generalize to NixOS, but then my live ISO gets stuck with the following error message:
[...]
Timed out waiting for device /dev/root, trying to mount anyway
mounting /dev/root on /iso...
mount: mounting /dev/root on /mnt-root/iso failed: No such file or directory
An error occurred [...]
How can I use my USB flash drive as both a live USB and as a storage device? I found this relevant Discourse link but there was no resolution to the problem there.
I realize this might not be the best place to ask this, but I figured that folks here would have expertise configuring boot partitions correctly.

For reference, the NixOS manual says I should dd the ISO to the disk directly: sudo dd if=<path-to-image> of=/dev/sdX bs=4M conv=fsync

 tim | I don't think that this will work since you need to unmount the live USB to format it as storage device | 07:16:00 |
| Raj | In reply to @tim92:matrix.org
I don't think that this will work since you need to unmount the live USB to format it as storage device Not sure what you mean, exactly. To clarify, I'm not trying to format the USB while it's live; I'm running this from an existing NixOS install.
If the"live USB" bit uses only ~1 GiB, there should be some way to make use of the remaining space, hopefully. | 07:57:47 |
