The most annoying thing for me was the huge internet data usage by snap updates but it is better now.
Even though it showed 300mb for a Firefox update, but only consumed 80mb and everything updated and working wonderfully ! 😅 😍 👑
The New app store is beautiful 🙌
(just sharing my experience 😅 )
I’ve seen very similar use of loop devices in an automotive app management implementation. Each app has its own filesystem image that gets mounted on a loop device on installation, then runs from it. It’s annoying on the command line but it’s not a bad use case of the facility. ☺️
