+## Traditional partitioning
+
+Create EFI partition.
+
+Create other partitions. F2FS and ext4 support per folder encryption (important
+in multi-user systems). BtrFS does transparent compression.
+
+### Encryption
+
+```
+cryptsetup --type luks2 luksFormat /path/to/device
+
+cryptsetup open /path/to/device mappername
+
+mkfs.filesystem /dev/mapper/mappername [-O encrypt]
+```
+
+
+### Swap file
+
+```
+# create file
+dd if=/dev/zero of=<partition or file> bs=1024 count=<number of KiB>
+
+chmod 600 <partition or file>
+
+mkswap <partition or file>
+swapon <partition or file>
+```
+
+From `/etc/fstab`:

+```
+<partition or file> none swap defaults,nofail 0 0
+```
+
+#### Encrypted swap
+
+For an ephemeral encrypted swap (no password, no hibernation), waiting on a

+Inside `void.d` configuration files for dracut and the kernel tasks in Void can

+## Configuring chroot installation
+
+Using `xvoidstrap` and `xchroot`, it is easy to install and enter a chroot
+installation. Might require installing the `linux` package and generating
+initramfs.
+
+- Allow `wheel` group to use `sudo`. Example file in `void.d`.
+- Create user in `wheel` (superuser) and `video` (backlight) groups.
+- If using `fscrypt` (F2FS and ext4), init it (rules and commands in Arch Wiki).
+- Configure Dracut in `/etc/dracut.conf.d/`.
+
+## Configuring any installation
+
+- Configure locales in `/etc/default/libc-locales`.
+- Configure AppArmor in `/etc/default/apparmor`.
+
+- Stow stuff and good to go.

-## Installation steps
-
-### Partitioning and creating filesystems
-
-Partitioning was manual. A UEFI setup can have only an ESP partition and the
-main user one. Partitioning can be done with either `gdisk` (more CLI-y) or
-`cfdisk` (more TUI-y). The ESP partition should be formatted as FAT32, and the
-user one should be made into a LUKS2 volume via
-
-````````
-cryptsetup --type luks2 luksFormat /path/to/device
-````````
-
-This will ask you for the desired password and encryption scheme.
-
-To open the LUKS volume, run
-
-````````
-cryptsetup open /path/to/device mappername
-````````
-
-This will create a device in `/dev/mapper` named `mappername`. This device can
-then de formatted with your filesystem of choice. I tend to go either with
-Brtfs, ext4 or F2FS. The last two support per folder encryption if you want to
-have another layer of protection (can be specially relevant in a multi-user
-setup). Formatting is done by
-
-````````
-mkfs.filesystem /path/to/device [-O encrypt]
-````````
-
-The filesystem should now be ready to be used!
-
-### Installing the root filesystem
-
-The current installation setup was made by downloading a ROOTFS image from the
-[Void Linux download page](https://a-hel-fi.m.voidlinux.org/live/current/) and
-untarring it into the root of the desired filesystem.
-
-````````
-tar xvf void-x86_64-ROOTFS-20191109.tar.xz
-````````
-
-TODO: chroot into, DNS, install basic stuff (iwd and neovim, mostly), install
-Linux, create initramfs, reboot, log into root, allow wheel to access stuff,
-create user with certain groups, init fscrypt (copy rules from Arch Wiki), git
-clone package, stow stuff, run startsway.
