The travis build failure are due to the time limits. Most of the datakit ones seems to be due to camlzip:

=-=- camlzip.1.07 troubleshooting -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
=> This package relies on external (system) dependencies that may be missing. `opam depext camlzip.1.07' may help you find the correct installation for your system.

This can be merged once the linked PRs are merged with upper bounds

I filed janestreet/core_extended#15 for the Alpine breakage but am inclined to merge this; do you think a patch is possible for Alpine support @diml?

Also it would be useful to have ocaml-version < 4.05.0 constraints due to

# File "src/core_unix.mli", line 398, characters 0-858:
# Error: This variant or record definition does not match that of type
#          Unix.open_flag
#        The field O_KEEPEXEC is only present in the original definition.

For core_extended yh we need to start using configurator to avoid future issues. I'll prepare a minor release for the core issue
