Bug#984617: unblock: lowmem/1.49

[Samuel Thibault <sthibault@debian.org>]

Package: release.debian.org
Severity: normal
User: release.debian.org@packages.debian.org
Usertags: unblock

Hello,

I have uploaded a new version of lowmem, see the attached patch.

[ Reason ]
This updates the memory levels at which the d-i enables low-memory
optimizations.

[ Impact ]
If this isn't getting updated, starting the d-i on an amd64 machine with
an amount of memory between 550MB and 780MB, with default parameters,
will try to install without any low-memory optimization, but that will
fail with OOM errors.

[ Tests ]
I tested the d-i image in each modified case.

[ Risks ]
The code change is trivial: it only changes the numerical level.

[ Checklist ]
  [X] all changes are documented in the d/changelog
  [X] I reviewed all changes and I approve them
  [X] attach debdiff against the package in testing

unblock lowmem/1.49

Thanks!
Samuel

 In both cases, you need to set min to absolute minimum amount of memory needed

 Ideally, constraints should be tested for both netboot and businesscard images
 (businesscard CD will use slightly more memory before partitioning that netinst
 because of mirror selection).

 NB: the minimum memory required to run the graphical installer must
 also be tested. See rootskel (debian-installer.d/S60frontend).
