I am almost 100% sure that I once saw a video of Stéphane Graber showing the development flow of LXD. It showed him doing interactive rebase on the command line, to pick changes to accept, and IIRC showed him using a custom script they used for LXD’s specific workflow.
I thought it would be LXD’s development process on the LXD YouTube channel, but it wasn’t. So maybe it was part of a conference talk or something…
Having searched the internet in vain, I thought if anybody would know the video I am talking about, they would be here.
