title: 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](./mountain.html)).
I now try to bring it with me and use it wherever, just to add to the list on
this page.

## Alpine setup
[wsinatra](https://lambdacreate.com) 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= cryptdm=lvmcrypt"
```
Also check this:
```
modules=sd-mod,usb-storage,ext4,cryptsetup,keymap,cryptkey,kms,lvm
root=UUID=
```
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 \

cat </usr/share/X11/xorg.conf.d/20-keyboard.conf
adduser -g lucidiot lucidiot
```
9. Use `visudo` to allow `lucidiot` and add `Defaults insults`
10. Edit `/etc/conf.d/bootmisc` to set `wipe_tmp` to `YES`
11. ```
rc-update del networking boot
rc-update del wpa_supplicant boot
rc-update del wpa_cli boot
rc-update add dbus default
rc-update add fuse default
rc-update add networking default
rc-update add wpa_supplicant default
rc-update add cpufreqd default
rc-update add tlp default
rc-update add bluetooth default
rc-update add swap default
rc-service dbus start
rc-service fuse start
rc-service lightdm start
```
12. Login into XFCE, check everything works
13. `rc-update add lightdm default`
