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.

* <https://wiki.alpinelinux.org/wiki/LVM_on_LUKS>
* <https://wiki.alpinelinux.org/wiki/Xfce_Setup>

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 \
           xf86-video-intel \

           xf86-input-libinput \
           xf86-input-evdev \
           xf86-input-wacom \
           setxkbmap \
           elogind \

           gvim \
           xfce4-screenshooter \
           syncthing \
           xfce4-whiskermenu-plugin \
           onboard \
           evolution \
           vlc \
           openssh \
           tlp \
           cpufreqd \
           blueman \
	   pipewire-alsa \
	   pipewire-pulse \
	   wireplumber
   
   cat <<EOF
   Section "InputClass"
           Identifier      "Keyboard Default"
           MatchIsKeyboard "yes"
           Option          "XkbLayout" "fr"
           Option          "XkbVariant" "oss"
           Option          "XkbOptions" "compose:rctrl"
   EndSection
   EOF >/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`
