Hi,

I'm debugging strange issue that do_rootfs task took ~50 minutes. I
enabled buildstats and from that I learned it's quite long. Any ideas
how to debug this issue? My idea was to add timestamp to do_rootfs
tasks but I'm not sure if it's even possible. Thanks.
how big is the image its creating, might affect the time. Secondly
use some system perf monitor to see which tool is taking so long.
Image is ~1GB so I would say quite
I can see that python3 took ~75-100% cpu when doing do_rootfs. We
tested on 16.04 + 18.04 Ubuntu server it's same.
Which perf monitor you had in mind? Thanks.
