I may be giving a workshop on livecoding audio in C early next year, but setting everything up on ~10 different Linuxes would take all the time. It doesn't work on Windows (probably no technical reason why something similar couldn't be constructed) nor macOS (likewise) but as I don't use them I'm not motivated to do the work.

So I'm thinking of making a live USB distro using debian-live live-build etc, but now I'm worried that modern "secure boot" nonsense on PCs will prevent booting from USB and we'll be stuck anyway. Remembering the immense waste of time spent trying and failing to get Puredyne to boot on stock Apple hardware more than a decade ago....

Anyway, this guide for adding persistence to the live USB (so you can save your work and configuration changes between reboots in an (optionally encrypted) overlay partition) is super nice:

Had some issues with scripting fdisk, some timing race condition prevents the kernel rereading the partition table - unplugging and replugging the USB device fixes it.

@mathr Are linux distros so different? Otherwise you could restrict the workshop user base to linux users and give every potential parttaker an online tutorial upfront.


Not sure how it'd work in practice.

Pre-Pipewire, configuring audio properly has been a recurring nightmare, often with Either/Or (Not Both) choice between "consumer audio" (i.e. Youtube works) vs "pro audio" (i.e. you can use JACK to interconnect applications).

And if I break Youtube for all the workshop participants' main laptop installs that's probably what they'll remember most about the workshop...

@mathr Yes those things should not happen. That is why i proposed to supply an online doc for people to go through before they take part in your workshop. So if Pipewire is needed already installed and working, than you'll them so. The Youtube issue ... belongs into "precautions" :D

@mathr you could try to force update of partition tables by the kernel using partprobe or kpartx.

@aggaz Thanks, I think I have a working script now, using `partprobe` as well as lots of `sleep` between `echo`ing characters into `fdisk`. Will put it online later.
