Also, when to use %i vs. %I ? I'm trying to use a postfix instance called "per-jessen" - with this, in the service unit I get:

%i = per-jessen %I = per/jessen %f = /per/jessen

According to the man page, %I is the unescaped value??

Systemd replaces (escapes) "/" with "-".

Ah, yes, I think I saw that mentioned somewhere. But that doesn't explain why it does the reverse too? I mean, my instance name "per-jessen" becomes "per/jessen" with %I ?

Difference between %I and %f matters mostly for mount units - systemd skips leading "/" so name for mount unit for /tmp is tmp.mount. %I would give you back "tmp" and %f - /tmp.

Ah, I see, thanks.

In general you should use %I or %f and escape instantiated name appropriately. Not sure if 13.2 already has it, upstream now offers systemd-escape helper to do it.

I don't see that helper in 13.2 yet - can you describe what you mean by "escape instantiated name appropriately" ? I did try using %I, but when it translates my hyphen to a slash, it doesn't work. thanks Per -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I am creating a postfix service unit with support for multiple instances.

I tried adding this:

ExecStartPre=/etc/%i/system/config_postfix ExecStartPre=/etc/%i/system/update_chroot ExecStartPre=/etc/%i/system/update_postmaps

which doesn't seem to work. I guess there's no instance id substitution in the name of the executable, only in the arguments? It isn't really clear from the man page.

Current upstream systemd.service(5) says

The command line accepts "%" specifiers as described in systemd.unit(5). Note that the first argument of the command line (i.e. the program to execute) may not include specifiers.

Thanks, I had only read systemd.unit(5). /Per -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Wouldn't something like the following work, then? ;-)

ExecStartPre=/bin/bash /etc/%i/system/config_postfix

Yup, that's what I did too initially, later I just commented out those -pre scripts. /Per -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

How is what you are doing now different from what you were doing here http://lists.opensuse.org/opensuse/2014-08/msg00333.html

... Which I found when googling for "systemd postfix multiple instances"

Haha, good find! I was obviously working on the same back then :-) I guess I have just reinvented the wheel - oh well. IIRC I ran into a network issue and had to give up.
