Re: Fedora 32 system-wide change proposal: reduce installation media size by improving the compression ratio of SquashFS filesystem

Thanks everyone for your comments. These are all valid concerns.

I filed a new change proposal at https://fedoraproject.org/wiki/Category:Changes/OptimizeSquashFS.

I'll run more benchmarks, including using Zstd compression algorithm, and will post results.
Hopefully this weekend, I'll also try to measure the impact of the compression, block size versus installation time.

Also, the decompression of SquashFS is currently happening in single thread. This could be changed with CONFIG_SQUASHFS_DECOMP_MULTI_PERCPU kernel build-time configuration option. I'll file a new change proposal for it, along with benchmarks.

Why stacked images? Consider a single base.img that's maybe 1G, and
now you don't have to do separate composes for server, cloud, GNOME,
KDE, Cinnamon, LXQt, Astronomy that repeat a lot of the same steps,
including expensive steps like compressing the same things over and
over again. Just do a 'dnf group install' tacked onto that base.img,
the work being done is custom for that output, rather than repetitive.
Not complicated. It would be fast enough that the high level variants
could be composed on demand. Seconds. It'd be fast enough to queue it
for download within the hour.

Well, I would like that.
