[Bug 2038906] [NEW] Mantic ISOs are around 700MB larger than mantic legacy ISOs

[Daniel van Vugt]

Public bug reported:

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-desktop-amd64.iso: 4.8GB
mantic-desktop-legacy-amd64.iso: 4.1GB

Digging into the ISOs shows where the difference is:

mantic-desktop-amd64.iso:/casper:
...
277	minimal.standard.enhanced-secureboot.squashfs
291	minimal.enhanced-secureboot.squashfs
413	minimal.standard.squashfs
777	minimal.standard.live.squashfs
1654	minimal.squashfs
3737	total

mantic-desktop-legacy-amd64.iso:/casper:
...
2873	filesystem.squashfs
2990	total
