# Title: Install LMDE (Linux Mint Debian Edition) 17 with LVM on LUKS (encryption) & hibernation support
#
# Description: These are very rough notes for installing LMDE with
#   encryption via LVM on top of LUKS.
#     - This includes SWAP being within LUKS
#     - Includes fixing hibernation (which will also apply to Debian Jessie or greater)


########
# 1. Boot from LMDE DVD/USB/...


########
# 2. Wipe the target drive and create partitions
#  - be careful since the primary disk may be detected at a different path than /dev/sda
#  - the following will
#    - create a traditional msdos (not GPT) MBR since my BIOS doesn't work with GPT
#    - create a 300MB /boot partition
#    - use the rest of disk for the LUKS encrypted volume

sudo - su # everything needs to be done as root

dd if=/dev/zero of=/dev/sda iflag=nocache oflag=direct bs=4096

apt-get install parted
parted -a optimal /dev/sda

print
mklabel msdos
unit mib
mkpart primary 1 300
set 1 boot on
mkpart primary 300 -1
print
quit


########
# 3. Encrypt, format, and mount
cryptsetup luksFormat -c aes-xts-plain64 -s 512 -h sha512 -i 5000 -y /dev/sda2
cryptsetup luksDump /dev/sda2 # check your work


cryptsetup luksOpen /dev/sda2 lvmlocal

pvcreate /dev/mapper/lvmlocal
vgcreate lvmlocal /dev/mapper/lvmlocal
lvcreate -L 16G -n swap lvmlocal
lvcreate -L 20G -n root lvmlocal
lvcreate -l 100%FREE -n home lvmlocal

lvs # check your work

mkfs.ext4 /dev/sda1
mkfs.ext4 /dev/mapper/lvmlocal-root
mkfs.ext4 /dev/mapper/lvmlocal-home
mkswap -f /dev/mapper/lvmlocal-swap
swapon /dev/mapper/lvmlocal-swap


mkdir /target
mount /dev/mapper/lvmlocal-root /target
mkdir /target/boot /target/home
mount /dev/mapper/lvmlocal-home /target/home
mount /dev/sda1 /target/boot

# 4. Start installer
# - Click: Menu -> Administration -> Install Linux Mint
# - For the partitioning choose: (Advanced) manually mount
# - After the 1st part of the installer process completes, continue with steps below



# 5. A few extra steps to make the system ready

# 8. All done. Test hibernation if you like
