install.sh: check destination for SERVICE_DIR_SYSTEMD_SYSTEM about pmocr HOT 6 CLOSED

Fact is that /etc/systemd is a symlink on redhat / centos / fedora* that points to /usr/lib/systemd.
Could you tell me if the Debian version of that dir is a link, and in that case, give me the destination ?

On the debian distro I'm using, it is a regular diretory under /etc/systemd

The systemd man page for file-hierarchy will probably be a better reference than an individual distro. To me it sounds like /etc/ is where all the system specific individual configs are located, whereas /usr/lib us where all the distro-specific configs are located. Clearly redhat does things their own way as you have described.

• ref: man file-hierarchy

when I ran install.sh it just copied pmocr-srv.service to the /usr/lib/systemd/ folder and named the destination file "system" since the directory didn't exist. Switching the SERVICE_DIR_SYSTEMD_SYSTEM target to /etc/systemd/system resulted in the correct copy operation

A more common Debian distro to compare against might be Ubuntu, however a cheap OCR server on a Raspberry is also pretty handy use of $35 especially when paired with a cheap duplexing scanner.

Very useful script! Thanks for making it easy to read through all the code.

Well, according to this, /usr/lib/systemd/system is a good place to place unit files. I wonder why Debian doesn't have that.

A good compromise would be to put files in /lib/systemd/system which works for both CentOS (/lib is a symlink to /usr/lib in CentOS) and Debian without using /etc/systemd/system path which isn't supposed to be used by installed packages.

I've setup a debian 8 VM to test this, seems to work.
Seems that redhat doesn't do things their own way after all.

Can you confirm latest commits work for you ?

from pmocr.

For my own installation I simply modified the install.sh code from build 2016050901 to reflect /etc/systemd/system and it works fine for me. Since I am already using it in a production environment and it works well I hesitate to reinstall just to test.

That being said I did take a look at my local /lib/systemd/system used in build 2016052501 and there are numerous .service files there as well, so I'll hazard a guess that using that directory will be effective.

If I do end up having to reinstall or upgrade following any future commits I'll keep an eye on that element and update this thread. I suspect it will work perfectly.

Thanks for taking a look at this!

Anyway, thanks :)
