Although I've had Extroot on USB for a while - docs made it simple - I'm still new to oWRT so go easy on me.
I got larger USB and decided to take my oWRT installation seriously - in terms of security - and I thought I should start by encrypting my USB, so..
inasmuch as luks-encrypting a block device seems same easy as everywhere, I failed to find any info on how to auto-open such encrypted device, so device mapper will do that @boot.
Is that possible without any "hackery" ?
Then, if above is possible - which I thought it'd be in 2022 by "standard" - then would Extroot be possible on such block device?
