Inconsistent ESP sizes

[Dimitri John Ledkov]

It seems that ESP sizes differ between
* desktop
* server subiquity
* server maas
* server preinstalled
* cloud-images

I see numbers like 512MiB, 538 (?!), 204 (?), 106MiB.

I guess all of them should be 512MiB. But I guess increasing ESP size can be seen as a regression by cloud images.

looks like different architectures do have different ESP's for cloud images:

arm: 204 : https://git.launchpad.net/livecd-rootfs/tree/live-build/ubuntu-cpc/hooks.d/base/disk-image-uefi.binary#n36
riscV: 106: https://git.launchpad.net/livecd-rootfs/tree/live-build/ubuntu-cpc/hooks.d/base/disk-image-uefi.binary#n49
amd64: 106: https://git.launchpad.net/livecd-rootfs/tree/live-build/ubuntu-cpc/hooks.d/base/disk-image-uefi.binary#n74

there might be an impact with upsizing them, what's the impact of their being inconsistent?

I have to say I think I spent about 5ms thinking about the size to use in subiquity. I guess it may make sense for subiquity to have a larger default because it is at least possible to imagine other operating systems being installed alongside Ubuntu for its use case, which is not really the case for MAAS or cloud images.
