I want to use ssh on a raspberry pizeroW to make persistent on-boot sshfs mounts to a central fileserver machine.
I do not want the pi's mount target to query id_rsa passphrase every login/boot/mount.
In kubuntu I use kwallet to remember the key passphrase, so simply by logging into the GUI all of my sshfs mounts work without passphrase query.
I want to do the same/similar on the headless and generally unattended pizero, which is console only (no GUI).
There is a kwalletcli package, but thats 250MiB of associated software, which seems excessive for a pizero, and i'm not even sure if it's going to work, or is the appropriate package.
I've tried the 'keychain' package, and that almost does what I want, except that it queries key passphrase on each reboot. That's exactly what i need it to NOT do.
