tank

A Lenovo ThinkPad X201 Tablet. My first ever ThinkPad, a very useful tool for my studies. It has been my daily driver, on and off, for over a year and a half in total. I really like it when I compute on the go, especially on trains or on mountains (not to be confused with mountain). I now try to bring it with me and use it wherever, just to add to the list on this page.

Alpine setup

wsinatra got me interested in Alpine, and I am having issues with Ubuntu 20 on most computers with tank being the worst affected, so I switched to Alpine. Below are some notes on the initial setup process.

  1. Go through setup-alpine until the disk prompt, then ^C

  2. apk add lvm2 cryptsetup parted haveged e2fsprogs syslinux
rc-service haveged start
parted -a optimal

# Inside parted
mklabel msdos
mkpart primary ext4 0% 100M
mkpart primary ext4 100M 100%
set 1 boot on
# Check that everything looks right
print
quit

haveged -n 0 | dd of=/dev/sda2
cryptsetup luksFormat /dev/sda2
cryptsetup luksOpen /dev/sda2 lvmcrypt

pvcreate /dev/mapper/lvmcrypt
vgcreate vg0 /dev/mapper/lvmcrypt
lvcreate -L 9G vg0 -n swap
lvcreate -l 100%FREE vg0 -n root
# Check that everything looks right
lvscan

mkfs.ext4 /dev/sda1
mkfs.ext4 /dev/vg0/root
mkswap /dev/vg0/swap
swapon /dev/vg0/swap
mount -t ext4 /dev/vg0/root /mnt/
mkdir -v /mnt/boot
mount -t ext4 /dev/sda1 /mnt/boot
setup-disk -m sys /mnt/

echo "/dev/vg0/swap\tnone\tswap\tdefaults\t0 0" > /mnt/etc/fstab

  3. Add cryptsetup and keymap to the features in /mnt/etc/mkinitfs/mkinitfs.conf

  4. mkinitfs -c /mnt/etc/mkinitfs/mkinitfs.conf -b /mnt/ $(ls /mnt/lib/modules/)
blkid -s UUID -o value /dev/sda2 > ~/uuid

  5. Set the proper UUID in /mnt/etc/update-extlinux.conf:

    default_kernel_opts="… cryptroot=UUID=<THE UUID> cryptdm=lvmcrypt"

    Also check this:

    modules=sd-mod,usb-storage,ext4,cryptsetup,keymap,cryptkey,kms,lvm
root=UUID=<UUID of /dev/mapper/vg0-root>
  6. chroot /mnt/
# This may cause errors on `/boot`, ignore them
update-extlinux
exit
dd bs=440 count=1 conv=notrunc if=/mnt/usr/share/syslinux/mbr.bin of=/dev/sda
cd
umount /mnt/boot
swapoff /dev/vg0/swap
umount /mnt
vgchange -a n
cryptsetup luksClose lvmcrypt
reboot

  7. Enable the edge repos in /etc/apk/repositories

  8. apk update
setup-xorg-base xfce4 xfce4-terminal lightdm-gtk-greeter xfce4-screensaver dbus-x11 sudo
apk add \
