This script's purpose is to set up a new system while minimising the efort. It's not neat and tidy - I only use it once in a while. It's developed for my choice of distro - Linux Mint and my setup of personal machine - it needs to run games and neovim alike. There is no guarantee that it will work or even suit YOU. Now that you've been warned - use it, take inspiration and let mee know if you have any feedback.
install_me.sh has some notes on recommended steps, take a look.
Below is a manual for crytsetup. This is a distillation of nixCraft's
article
KEYFILE=/etc/backup_keyfile
DEVICE=/dev/sdb
DEV_NAME="backup"
# keyfile creation is in install_me.sh
# Prepare volume (All data will be lost!)
shred -v --iterations=1 $DEVICE
cryptsetup luksFormat $DEVICE
cryptsetup luksAddKey $DEVICE $KEYFILE
cryptsetup luksDump $DEVICE # verify
mkfs.ext4 /dev/mapper/$DEV_NAMEAdd following to /etc/crypttab:
backup /dev/sdb /etc/backup_keyfile luks
Add following to /etc/fstab:
/dev/mapper/backup /backup ext4 defaults 1 2
Backup itself will be added later :)
