Thanks for reporting this! It looks like we need to handle this kind of error better.

@RochesterinNYC, this would be a good bugfix ticket I think--if the default home directory compact index destination isn't writable, we should use a tmp dir instead.

[RochesterinNYC]

Yup, sounds like a nice GSoC PR opportunity.

[b-ggs]

I'll work on this!

Permission errors will be changing due to #5007 in 1.14, so I think it's safe to close this (and re-open if needed at a later date)
