Do you have any idea what process could have been using /var/mero/? (‘run-st’ passes on my machine...)

have no idea, I've restarted the test once again

@chumakd May I ask you to remove h0 start line from the Xperior script?

@vvv done, updated Jenkis test is running

Don't know why git cannot detect this rename.

@vvv The answer may be found in git help diff manpage (look for option -M):

The default similarity index is 50%

So if files differ more than that threshold they are not considered as a rename.

Xperior script fails, because h0 start command doesn't exist any more.

> cd /root/build//halon && ./scripts/h0 start
Invalid command: start
Type `h0 help' for usage.

This scenario is covered by h0 run-st and is not needed any more.

I did git mv -f scripts/h0{-new,}.

$ cmp <(git show d1570442f:scripts/h0-new) <(git show 8895aadef:scripts/h0)
$
