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 am looking into switching it to Alpine.  This section has some
notes on setting it up with LVM on LUKS on a virtual machine before I really
switch to it; encryption really matters to me on this specific laptop because
I carry it everywhere.

* <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`
3. `rc-service haveged start`
4. `parted -a optimal`
   1. `mklabel msdos`
   2. `mkpart primary ext4 0% 100M`
   3. `mkpart primary ext4 100M 100%`
   4. `set 1 boot on`
   Use `print` to check.
5. `haveged -n 0 | dd of=/dev/sda2`
6. `cryptsetup luksFormat /dev/sda2`  
   TODO: try `cryptsetup -v -c serpent-xts-plain64 -s 512 --hash whirlpool --iter-time 5000 --use-random luksFormat /dev/sda2`
7. `cryptsetup luksOpen /dev/sda2 lvmcrypt`
8. `pvcreate /dev/mapper/lvmcrypt`
9. `vgcreate vg0 /dev/mapper/lvmcrypt`
10. `lvcreate -L 9G vg0 -n swap`
11. `lvcreate -l 100%FREE vg0 -n root`  
    TODO: Also add a separate volume for /home
12. `lvscan` to check
13. `mkfs.ext4 /dev/sda1`
14. `mkfs.ext4 /dev/vg0/root`
15. `mkswap /dev/vg0/swap`
16. `swapon /dev/vg0/swap`
17. `mount -t ext4 /dev/vg0/root /mnt/`
18. `mkdir -v /mnt/boot`
19. `mount -t ext4 /dev/sda1 /mnt/boot`
20. `setup-disk -m sys /mnt/`
21. Add `/dev/vg0/swap\tswap\tdefaults\t0 0` to `/mnt/etc/fstab`
22. Add `cryptsetup` and `keymap` to the `features` in `/mnt/etc/mkinitfs/mkinitfs.conf`
23. `mkinitfs -c /mnt/etc/mkinitfs/mkinitfs.conf -b /mnt/ $(ls /mnt/lib/modules/)`
24. `blkid -s UUID -o value /dev/sda2 > ~/uuid`
25. 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>
    ```
26. `chroot /mnt/`
27. `update-extlinux`  
    May cause errors on `/boot`, ignore them
28. `exit`
29. `dd bs=440 count=1 conv=notrunc if=/mnt/usr/share/syslinux/mbr.bin of=/dev/sda`
30. `cd`
31. `umount /mnt/boot`
32. `swapoff /dev/vg0/swap`
33. `umount /mnt`
34. `vgchange -a n`
35. `cryptsetup luksClose lvmcrypt`
36. `reboot`
37. Enable the community repo in `/etc/apk/repositories`
38. `apk update`
39. `setup-xorg-base xfce4 xfce4-terminal lightdm-gtk-greeter xfce4-screensaver dbus-x11 sudo`
40. `apk add xf86-video-intel xf86-input-synaptics xf86-input-mouse xf86-input-keyboard setxkbmap elogind polkit-elogind gvfs-fuse gvfs-mtp fuse-openrc thunar-volman udisks2`
41. Update the Xorg config:  
    ```
    Section "InputClass"
    	Identifier	"Keyboard Default"
	MatchIsKeyboard	"yes"
	Option		"XkbLayout" "fr"
	Option		"XkbVariant" "oss"
	Option		"XkbOptions" "compose:rctrl"
    EndSection
    ```
42. `adduser -g lucidiot lucidiot`
43. `visudo` to allow `lucidiot`
44. `rc-service dbus start`
45. `rc-update add dbus`
46. `rc-service lightdm start`
47. Once everything works, `rc-update add lightdm`
48. `rc-service fuse start`
49. `rc-update add fuse`
