The installer itself will run that?

I see from here

  https://forum.snapcraft.io/t/development-sprint-march-5th-2018/4345/11

"At the refresh attempt, if inside a hold window, skip it as long as it
doesn’t go beyond the maximum number of days (60 days right now)

Must warn if requested hold cannot be respected due to maximum period"

It doesn't say what the maximum number of days is since - do you know?
If it it since the last refresh, is that the date that the image was
created? If so, what happens if your image is more than 60 days old? It
sounds to me like this spec won't let you hold refresh in that case.
Have you checked this?

Probably easier if I just comment on that thread:

Title:
  Live images should be able to turn off Snap updates

Status in snapd:
  Confirmed
Status in casper package in Ubuntu:
  New

Bug description:
  There should be a way to turn off Snap updates while allowing Snaps to
  still run.  When Live CD images start having Snaps installed by
  default they won't want the packages to be updated while in live mode
  but they will want applications to be runable.

  Probably there should be a setting for this and Casper should be
  easily able to set that setting.
