lucidiot's cybrecluster

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.

Specifications

Places it went to

Just taking it with me without doing anything does not count; I have to turn it on and use it for a place to enter this list. This list is unordered. I sometimes add some fun things I did in each place, when I remember them.

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 \

  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
