Bug Description
Mantic ISOs are around 700MB larger than mantic legacy ISOs. That's 500MB-600MB more than I'd expect from just the new installer.
For example 2023-10-10:
mantic-
mantic-
Digging into the ISOs shows where the difference is:
mantic-
...
277 minimal.
291 minimal.
413 minimal.
777 minimal.
1654 minimal.squashfs
3737 total
mantic-

2873 filesystem.squashfs

It is not just a new installer. It is also new install targets (TPM FDE) that require new squashfs layers.
There are some gains to be made by reducing duplication between some of the layers (minimal. standard. enhanced- secureboot. squashfs and minimal. enhanced- secureboot. squashfs should not ship the snaps, we should figure out how to put all of these in the minimal layer as preseeding and ensure they get removed from the target when doing a non-enhanced- secureboot install; and kernel debs should not be duplicated between the live layer and the package pool). But this work is not going to be done in mantic.
