This doesn’t solve your present problem but maybe it helps to avoid it in the future.
Instead of physical volumes, you could use thin provisioned logical volumes. LVM is the word here. These would allow you to maintain volume division without fixing the sizes rigidly.
Another way to do this would be to use a BTRFS filesystem, and it’s subvolumes as ‘real volumes’. The semantics would be the same.
Yeah, for example, it’s nice not having to manually fiddle with PHP dependencies etc. when it comes to web servers, but desktop apps are rarely like this. They just have their executable, and seldom require any serious configuration.
It’s interesting to compare these package managers to service containerization, I.e docker, podman etc. There it works pretty well, but many of these benefits don’t seem to be present in desktop use.
