> Having worked on migrations of a Sling derivate Ruben & I ran into issues where the /etc/map would map to production instead of testing environment.
>  Many big customer have extensive /etc/maps and also many different environments like dev, qa, staging, prod etc.
>  It would be great to have a tool where for example items like the host name or external links in /etc/map could be configured outside so that just one entry has to adjusted rather than creating a full copy of the /etc/map tree.
>   
>  Example:
>   
>  /etc/map/http/{{{{phv.fq.host.name}}}}.8080
>   
>  Placeholder provides:
>  DEV: phv.fq.host.name=localhost
>  QA: phv.fq.host.name=qa.author.acme.com
>  STAGING: phv.fq.host.name=[staging.author.acme.com|http://staging.author.acme.com/]
>  PROD: phv.fq.host.name=[acme.com|http://acme.com/]
>   
>  At runtime these are the resolved values:
>  DEV: http/localhost.8080
>  QA: http/qa.author.acme.com.8080
>  STAGING: http/[staging.author.acme.com|http://staging.author.acme.com/].8080
>  PROD: http/[acme.com|http://acme.com/].8080
>   
>  Not only does that make it easier and faster to create new test environments but it also cuts down on the chance of copy-n-paste errors.
>   
>  I have a working POC with an PlaceholderProvider OSGi service and an enhanced MapEntries that resolved any placeholders if found.
>   
>  Attached are 3 screenshots:
>  1. OSGi Placeholder Provider Configuration
>  2. /etc/map (Composum)
>  3. Result of [http://andreass.local:8080/] call
