Add Installation Support For Devuan

Here's a working branch for OpenSRF: https://git.evergreen-ils.org/?p=working/OpenSRF.git;a=shortlog;h=refs/heads/user/dyrcona/devuan-install

Branch for Evergreen forthcoming.

Here's a working branch for Evergreen: https://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/user/dyrcona/devuan-install

Works for me with minimal testing.

I removed the pullrequest tag as this branch needs to be updated for new dependencies.

If no one wants to support installing on Devuan, then let me know. It works pretty much like Debian, and I may keep this branch around just for those who are interested. I do some of my testing and development on Devuan. If the Devuan community were larger/more active, I'd possibly use it in production.

I plan to update the branch for the most recent changes in Evergreen and OpenSRF soon.

I also intend to drop Devuan Ascii and add Devuan Chimaera. This may be done with brand new branches.

I am going to drop this effort for a while, at least until some of the other dependency branches are merged, i.e. removeal of Debian Stretch and addition of install prerequisites for newer PostgreSQL versions.

While the currently available Devuan release ship with PostgreSQL versions greate than 9.6, there is no PostgreSQL community apt repository for Devuan as there are for Debian and Ubuntu as far as I know. This may preclude us from ever officially supporting Devuan.

BTW, setting the status to confirmed after I see that 1 other perons says it affects them.

In the interest of conserving time and effort, I have set the Status of this bug for OpenSRF and Evergreen to "Won't Fix." I have not had time to keep the Devuan branches up to date and they are woefully behind current dependencies, etc., in the main OpenSRF and Evergreen branches.

If someone else wants to take this on and maintain it, I will be happy to review patches.

So, if you assign this bug to yourself, you can set the status back to "Confirmed."
