Is it just a compiler bug that it's moaning about this open?

[gaborigloi]

Maybe, I found this very puzzling. Maybe I should undo this change.

[gaborigloi]

Because the EEXIST variant is actually in the Unix module.

[jonludlam]

This is the bug that's affecting xcp-idl too - I've had to do precisely this change there. Quite annoying actually.

Don't despair... we will be able to move to 4.06.? soon ;)

[gaborigloi]

So that means this PR is good to go then? :)

[mseri]

I believe so

[gaborigloi]

The Travis failure is due to xenctrl :( xapi-project/ocaml-xen-lowlevel-libs#106
I'll switch it to CentOS

[mseri]

I don't understand why now it does not find xen-api-client-lwt, it is there: https://github.com/xapi-project/xs-opam/tree/master/packages/xs-extra/xen-api-client-lwt.master

It must be something to do with other packages

I'm looking into it, it's an issue with the docker script:

Step 3/11 : RUN bash -eux -c 'git remote set-url origin git://github.com/xapi-project/xs-opam && git fetch origin master && git reset --hard origin/master'
