IN SHORT:
0. increase size of outermost container (grow qcow2, dd disk to larger disk, etc.)
1. increase size of partition containing the encrypted volume set (cfdisk, fdisk, etc.)
2. unlock encrypted volume
3. grow LVM "physical volume"
4. grow LVM "logical volume"
5. check filesystem
6. grow filesystem
7. tidy up and test.

0. Don't have a SIM card in when you're updating radio firmware or it will bomb out partway through as it changes from internal IP to IP passthrough

1. Disable external IP passthrough mode: Network Setting -> Broadband -> Cellular APN -> #1 -> Modify icon -> "IP Passthrough" slider to off

2. Use "management" Wi-Fi AP as general Wi-Fi AP (with limitations) -> Network Setting -> Bridge1 -> Modify icon -> Move the Wi-Fi AP interface to the pane on the right alongside LAN1
NOTE: by default, once you do the above, the router will happily pass traffic from devices on the Wi-Fi AP to other devices on the LAN1 subnet, but will block traffic originating from the Wi-Fi AP from exiting to the Internet via the LTE side of the device. You can clumsily hack around this by setting another device, e.g. another Wi-Fi AP or Raspberry Pi or Cray supercomputer, as the default gateway for the LAN1 subnet in your DHCP server config, and pointing *that* device at the Zyxel as *its* default GW. This adds additional hops, but enabl

2024 ADDENDUM TO BELOW NOTES:
1. I have found that the linux-amd-znver3 kernel reliaby works for passthrough, initializing devices in a sane order and respecting boot-time blacklist kernel args https://aur.archlinux.org/packages/linux-amd-znver3
2. I have since managed to get the Nvidia RTX A2000 12GB working in passthrough with a few different settings which I will document here Real Soon Now, I Swear™.
3. The RTX 4000 SFF Ada Generation 20GB works as a drop-in replacement for the A2000.
4. Stability is not guaranteed - I don't know what to blame, but it's infrequent enough (i.e. one crash every few months) that I haven't spent time on it.
5. I have recently transitioned away from Arch to openSUSE Tumbleweed, which works out-of-the-box as a passthrough host and does not constantly break.
6. I am separately maintaning a variant of the linux-amd-znver3 and linux-amd-znver2 configs which have been tweaked to work on openSUSE. I can share these or even provide builds if there is interest.

2022 NOTES - FULLY WOR

## So you want to use stuff like 'tmux' and 'lolcat' on the Steam Deck, but they haven't been included in the base OS?
# One way to do it is this.
# 1. setup a chroot environment so there is a file structure in which Pacman can download/unpack packages and their dependencies.
# 2. don't use it as a chroot environment; rather, add the various /bin directories inside it to your $PATH, and create an /etc/ld.so.conf.d/deck-local-arch.conf to permit the bins to find the libs they need.

mkdir -p ~/.local/packer
cd ~/.local
#these steps are required, or else the pacstrap will fail with 'marginal trust' errors
pacman -Sy archlinux-keyring
pacman-key --populate archlinux

## this is peculiar to the picm4 with 200MHz dynamic downclock, which induces several seconds per second of clock drift. Sync with a local NTP server every 5 seconds of server time, ~10-15 seconds realtime, to keep things more-or-less in line.

## NOTE: files apparently have to end in .start or they will not be executed
## NOTE: commands have to exit or daemonize, or 'local' will fail to finish initialization and subsequent attempts to reboot will fail!

Run the following in a terminal:
sudo mdutil -Ea
sudo mdutil -ai off
sudo mdutil -ai on

Alternatively, use Automator to create an Application with a Run Shell Script Action containing the above and put it somewhere it's easy to access.
