##Working configuration to accomplish 0-downtime deploy with unicorn 5.x and systemd on centos 7

The scope is to accomplish a 0-downtime reload of a unicorn service managed by Systemd on a Centos 7 distro.

The examples and assumptions that i found on the bogomips's unicorn repo seems not working for centos 7.

Below a working configuration tested on Centos 7 and unicorn 5.1

Any advice/remark will be appreciated

Zendesk timezones are represented by friendly names that map to tz database names.
For example, an API request returns "Eastern Time (US & Canada)" instead of "America/New_York".
You can map the friendly names to the tz database names by referencing the Constants > Mapping
section of the Ruby on Rails TimeZone object doc.

The standard names for indexes in PostgreSQL are:

{tablename}_{columnname(s)}_{suffix}

where the suffix is one of the following:

• pkey for a Primary Key constraint;
• key for a Unique constraint;
• excl for an Exclusion constraint;
• idx for any other kind of index;
