Arch Linux on LUKS

Mostly follows the Arch Linux install guide, but with tips from these for the encryption setup:

• https://gist.github.com/binaerbaum/535884a7f5b8a8697557
• https://gist.github.com/OdinsPlasmaRifle/e16700b83624ff44316f87d9cdbb5c94
• https://wiki.archlinux.org/index.php/Systemd-boot#Standard_root_installations
• Uses an unencrypted /boot with LUKS on LVM for / (formated as btrfs)
• Uses UEFI so make sure system is booted in UEFI efivar --list or ls /sys/firmware/efi/efivars if there's output for the former or the directory exists for the laater system has booted in UEFI

Network

Use iwctl after booting with Arch ISO

Setup: UEFI, LVM + LUKS encrypted drive
Bootloader: Grub
Links:

Restore GRUB (boot into live env):

# get the encrypted partition (crypto_LUKS)
lsblk -f

Script that will trigger a local to remote sync when any changes below your local Google Drive folder occur - but at max. every 10 minutes - and a remote to local sync every x (e.g. 30 minutes) via a cron job.

0. Install rclone and configure it for Google Drive
1. Create files listed below
2. Configure rclone_watch_local.sh to be run on startup (e.g. using a systemd service unit)
3. Add a cron job that runs rclone_remote2local.sh every x (e.g. 30) minutes

shrink + compress virtual disk image in Qemu/KVM

originally from Martin Kopta's blog

Tue Apr 22 10:41:10 UTC 2014

In order to shrink virtual disk of your virtual machine (process called disk space reclamation) in Qemu/KVM, you can go with following. In your running virtual machine, fill all remaining empty space with zeroes. Then, shut down virtual machine and convert the disk image from original format to the same format (esentially doing nothing). In the process of conversion, Qemu will skip the zeroes and save you some space. You can even add some compression to save even more space.

root@vm# dd if=/dev/zero of=/file
root@vm# rm /file
