kind of a changelog of the dev branch about imagebuilder HOT 4 OPEN

btw. i also experimented with running an armv7l userland on aarch64 to save memory (armv7l has a something like 30% +/- lower memory footprint than aarch64 both on memory usage and filesize of binaries on disk) but finally gave up on it for the following reasons:

• i was not able to get firefox working stable with lots of tabs in such a setup - it always ended up with crashing tabs as soon as many of them were opened - i did not see this problem on native armv7l or running aarch64 natively on the same system
• compiling stuff and the kernel is not easy with such a setup as uname will report aarch64 which can confuse some configure scripts and for the kernel one needs an aarch64 chroot to compile in

it looks like the best approach to run for instance a firefox with about 40-50 tabs open on a 2gb aarch64 system is using zswap - in my tests so far it only resulted in minimal swapping (50-100mb)

I have flashed this test image, and so far using as a server without gui (lightdm disabled)
Idle instance without any apps running shows 0.20 load - is that normal?

from imagebuilder.

maybe this is top itself or some kernel daemons - looking at the top output for a while in H mode might give some clue ... also is the load usually averaged over some time, so maybe waiting a bit more might lower it even more ... maybe ubuntu is still doing some auto update checks on bootup too - i think i disabled quite a bit of that already but there might still some settings be left in /etc/apt/ ...

I made this screenshot in 1 hour 23 minutes after boot, so it was idling for quite long time. Never seen such high load on a clean system doing nothing

Will continue checking
