This worked before changes were made to the post-init script. Any idea?
Can you please post the full post init script here so we see what modifications you make!
The error we see in the video is definitely caused by a partclone parameter as mentioned by Tom. The issue is you use init file from 14.07.2019 (see in the video) which came with partclone 0.2.89 and modified the scripts to match parameters that only work with partclone 0.3.12 (which we updated to in September 2019).
So what you want to do is download the latest proper build of the inits and use those: https://dev.fogproject.org/blue/organizations/jenkins/fos/detail/master/105/artifacts
Not exactly sure about the error you posted on MacOS X. Please post the pull post-init script here so we know your mods.
Edit: Ahhh wait! The scripts only count NTFS adn EXT2/3/4 as possible resizable filesystems. So on your Mac it doesn’t find any and bails out. Which version of Mac OS X do you have? Resizable is a huge problem in Mac OS - see here: https://forums.fogproject.org/topic/13881/help-with-mac-imaging
