[systemd-devel] Fedora 16 and upstart

[Chinmay Mahata]

Hi, 

    Thanks a lot, everybody for your support, for quick and valuable comments. So it is time for me to write the systemd service scripts (and bite the bullet !!! to be frank, I am not feeling much confident).

Now I have few queries (may sound like dumb questions).

1. How can I call user-defined shell(bash) functions from the service scripts in ExecStartPre and ExecStartPost sections?
   Like I have a shell file "/home/me/my_functions_file", inside it, there is a function "foo_function". I used different ways (below) in my scripts but all failed miserably.

....
EnvironmentFile=/home/me/my_functions_file
ExecStartPre=foo_function param1

----------
ExecStartPre=/bin/bash /home/me/my_functions_file; foo_function param1

----------
ExecStartPre=/home/me/my_functions_file
ExecStartPre=foo_function param1

Nothing is working (strangely, not getting any error messages) !!!!


2. How can I run multiple instances of an executable with different arguments?


3. How can I use user-defined signals in the service scripts?


Please give me a few clues.

Best regards,
--Chinmay

Hi All,
    Sorry for asking such a noob question.

I am migrating my system from fedora 13 (fc13) to fedora 16 64-bit (fc16 x86_64) version. In fc13 all our module service scripts are written for upstart/initctl. In fc16, there is no upstart/initctl support any more, but there is systemd as the init system. 


Hi You do realise that F16 is EOL and won't receive any updates (not only systemd, but in general)? I'd strongly recommend using F18 instead.

So my queries are:

1. Is there any way I can reuse my upstart initctl scripts in fc16 x86_64?

2. What are items/things I need to do in fc16 so that I can reuse the old initctl scripts?


Please help me out by sending me your solutions/suggestions.

Upstart scripts aren't supported. You need to rewrite them as systemd unit files. If you're lucky, that isn't too much work though ;-)
Thanks in advance.

Best regards,
--Chinmay
