Arch install notes

9380 on Arch defaults to using s2idle instead of sleep for suspend so powerdrain is massive.

Fix is to add mem_sleep_default=deep to kernel cmdline and regenerate grub config

Yubikey card service

sudo systemctl enable pcscd.service
sudo systemctl start pcscd.service 
sudo systemctl status pcscd.service

Public GPG Key

$KEYID = "0x34132A8E9B2A857F" gpg --recv-keys $KEYID

Switching Yubikeys

Need to delete contents of $HOME/.gnupg/private-keys-v1.d/ that correspond to keygrips of keys, then run gpg --card-status to associate with new hardware key

Renewing subkeys

mount backup and import master key

Turn off network, mount device with master keys

gpg --import /path/to/mastersub2021.key

change expiry dates

set $KEYID, then

gpg --expert --edit-key $KEYID

Run, in sequence

key 1
key 2
key 3

to select all subkeys, then type expire (won't expire things) to change expiry date.

then type save and exit.

export

Now export the new public key

gpg --armor --export $KEYID > gpg-$KEYID-date.asc

unmount drive and nuke private key

gpg --delete-secret-key $KEYID

and then on in-use-machines

gpg --import gpg-$KEYID-date.asc

and trust

gpg --edit-key $KEYID

> trust
> 5

then gpg --card-status to confirm yubikey is working.
