Hello,
So Peter has merged this patch now and it has resulted in an increase of about 70M of the ISO image. This is expected since we are now compressing everything individually which will give us a worse compression ratio.
I assume that the updater would grow in a similar size which is probably acceptable to me.
Since we suffer from bloated Core Updates, I wanted to double-check with everybody that this is okay for everybody else, too.
Best, -Michael
Hello,
Something I forgot is that we should probably update the package. Since we are shipping everything again, we should at least ship the latest.
Is anyone up for this?

Hello Michael,
well, contrary to your expectation, shipping the compressed linux-firmware leads to an way too big update:
$ cat ./install/packages/meta-core-upgrade-166 Name: core-upgrade Summary: IPFire Core Update ProgVersion: 2.27 Release: 166 Size: 299315200 Dependencies: File: core-upgrade-2.27-166.ipfire Services: $ ls -lah ./install/packages/core-upgrade-2.27-166.ipfire -rw-r--r-- 1 root root 286M 24. Mar 10:43 ./install/packages/core-upgrade-2.27-166.ipfire
I do not have the figure ready how much of that 286 MByte are caused by linux-firmware, but it has to be way more than 100 MBytes. Otherwise, Core 166 would have been to big already, which I doubt when looking at the currently included filelists.
Thanks, and best regards, Peter Müller

Hello,
Oh, this would be entirely linux-firmware since the last nightly build generated an update for x86_64 of 7.8 MiB.
I find it very interesting to see that Zstandard is so much better at recompressing this. We use XZ for the core update, but the distribution image in the ISO file is compressed using Zstandard.
286 MiB is way too large and absolutely not worth it.
I will test a couple of things and will then get back to you.
Best, -Michael
