Mas 3.0 debianmake #1023

Closed martinsumner closed 4 years ago

martinsumner commented 4 years ago

Significant changes to debian make process. As rebar3_cuttlefish scripts are run as a pre-start hooks, it does not have root access to make links into running directory. To resolve this the riak script has been split into two parts riakpre and riakrun:

riakpre is run as root riakrun is run as riak

The cf_config script makes the links into a riak-controlled space (platform_gen_dir) and riakpre than makes the links from that place to the privileged directory configuration files.

When sudo riak start or sudo service riak start is called cf_config will create the initial links, but the actual config is read directly (not depending on the links). the linked version of the config is only required when running riak ping, riak stop etc and these will use the linked version - and as they only make sense after a riak start it can be assumed the links have already been made by cf_config.

To simplify, and workaround issues with config merging across profiles, more configuration (including standard rel vars.config) has been moved into debian vars.config. This leads to some repetition - but is easier to follow. so now the debian release only uses the deb profile, and not the rel/deb profiles combined.
