caem 4b6c921768 Use ftplugin instead of autocmds to set indent The autocmds approach had the issue of overwriting the indentation globally for all files. So if you opened a .nix file and then wanted to edit a .c file, it would then still do 2 space indentation when it should be 4. The autocmds approach was redundant in the first place as the ftplugin directory already exists for this exact purpose and does it without the aformentioned issue.		2024-05-26 11:43:53 +02:00

Installing

This configuration uses impermanence with btrfs snapshots so you'll have to partition your system in a certain way.

First you'll need this partition layout, assuming you're installing on nvme0n1.

DEVICE              FILESYSTEM      PURPOSE
/dev/nvme0n1
├─/dev/nvme0n1p1    vfat            EFI partition
└─/dev/nvme0n1p2    btrfs           Partition to house all the subvolumes

Inside of the btrfs root volume we're going to need 2 subvolumes.

SUBVOLUME           MOUNT           PURPOSE
root                /               Impermanent data
nix                 /nix            Permanent data

You'll also need to create a read-only snapshot of the root subvolume and call it root-blank.

After you've mounted all the subvolumes and EFI partition (/boot) in /mnt clone this repository in to /mnt/nix/config. Adjust all the block ids of the partitions in hardware-configuration.nix and create a hashed password using mkpasswd and store it in the secrets/{user} directory as pass.

Finally, in the config directory run nixos-install --flake '.#', reboot and you're done.
