[Bug 2038906] Re: Ubuntu desktop ISOs are around 700MB larger than legacy desktop ISOs

[Steve Langasek]

There's still work to be done to reduce duplication of contents between
the layers.  Reopening this bug because I'm not sure offhand where else
we're tracking that at the moment.

** Changed in: livecd-rootfs (Ubuntu)

Title:
  Ubuntu desktop ISOs are around 700MB larger than legacy desktop ISOs

Status in livecd-rootfs package in Ubuntu:
  Confirmed

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-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
