General setup of live arch VM

Setup on VM

• Boot the vm, select x86 / x86_64 and enter
• start ssh daemon:
  • systemctl start sshd
• change the root password
  • passwd

Setup ssh

• from the host, copy the local ssh key to the vm
  • ssh root@<server> -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null 'mkdir -pv /root/.ssh'
  • rsync -e "ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null" ~/.ssh/id_rsa.pub root@<server>:/root/.ssh/authorized_keys
• can now ssh in without password
  • ssh root@<server> -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null

Update packages

• optional: use a disk to save cached packages
  • mount the drive
  • mkdir -pv <DIR_TO_SAVE_CACHED_FILES>/{sync,pkg}
  • ln -sv <DIR_TO_SAVE_CACHED_FILES>/sync /var/lib/pacman/sync
  • rmdir /var/cache/pacman/pkg
  • ln -sv <DIR_TO_SAVE_CACHED_FILES>/pkg /var/cache/pacman/pkg
• refresh packages and update keyring
  • keyring must be updated first, else newer packages will fail verification
  • pacman -Sy --noconfirm archlinux-keyring
• do a full system update
  • pacman -Su --noconfirm
• make sure the package db is in latest db format
  • pacman-db-upgrade
