[Andreas Naumann]

Hi Thomas,

finally I found some time to try this v7 on top of 2019.02-rc1.

My update to the known remaining issues is:
1. I no longer see the ccache problem for the kconfig packages
(uboot+linux)

2. the package-file-list problem has become a blocker since commit
3c8f0d9 core/pkg-infra: restore completeness of packages files lists
with failures like

comm: /home/jenkins/.../build/.files-list-staging.new: No such file or 
directory

Would it be an idea to write the statistics per package :-) inside the 
package build folder and assemble them into one file only once all 
packages are built?

best regards,
Andreas




PS. Actually I just tried flock, which looks promising. If it works I'll 
send a patch next week.
