FYI: Big Wolfram 14 upgrade (plus many other upgrades) required a much bigger extend

(This isn't an error report, just an interesting case, I think...)

In my typical sdm invocations, I have sdm install a bunch of software, and also do a dist-upgrade, so I always extend the images to create enough space. On my full images, I normally do the following (extending the image by 2GB):
--extend --xmb 2048

When starting with the stock 2024-03-12 images, a really big Wolfram upgrade gets pulled in now during the upgrade, and I found that I had to bump up the extend by another 3GB, for a total of 5GB:
--extend --xmb 5120

I roughly binary-searched my way between extend totals of 2GB and 8GB, and I found that while 4GB wasn't big enough, 5GB was. I didn't try to fix the answer any finer than that, so the real required total is somewhere between 4GB and 5GB, and the required additional amount is something between 2 and 3 additional GB.

I looked at /etc/sdm/apt.log and /etc/sdm/history in the image, finding that a total of 79 packages needed upgrading, and that the dist-upgrade used up 1.9GB!:

Just an FYI, like I said...

Thanks for the heads up.

Note that you can also extend it significantly, do the install, and then shrink it afterwards if desired.
