Also, what is the effect on the user experience?  If the process is run
twice - even automatically - is this going to double the upgrade time from
20 minutes to 40 minutes?

Thanks,

Subject:  Re: [Fuel-dev] Do we really want to update docker during the
upgrade before HCF?

Just to clarify, are the upgrade instructions for 5.1 to run upgrade.sh
twice
or are you making ./upgrade.sh run itself twice for one user command?

I just created https://bugs.launchpad.net/fuel/+bug/1360372 to cover the
5.1 upgrade instructions.
