Hello,

Thanks for the patch, but this only solves one of my concerns.

What about printing the colourful exit status more than once?

Best,
-Michael

You mean the exit status for the 'stop'-section?

-v please.

'evaluate_retval' is now four times in, status output has been added.

Anything else?

LOL. Good one :)

So, you are launching vnstatd by calling loadproc.

That function will start the process and print “OK” or “ERROR” in a colour on the console.

Calling evaluate_retval (which should be called in loadproc, too) will then print OK again.

Did it not do that when you tested it?

Current version contains 'evaluate_retval' in all start/stop actions
plus output for 'status':

=>
https://git.ipfire.org/?p=people/mfischer/ipfire-2.x.git;a=blob;f=src/initscripts/system/vnstat;h=c1bb2942a897e0a4acab344c8e2c128d4542f958;hb=59b3afd07f55b93f4c96bfe63d0506494a46b5ff

Please check if this is ok now.

Hi,

Yes, but this script does not contain any evaluate_retval calls after loadproc/killproc:

I noticed that, but...

I saw that, too, but didn't think of ALL actions in that script.

Nope. Doing it that way was a bit unfamiliar but I'll get used to it.

I had to take a look at the other inits and 'functions.pl'.

Now I finally know where the colorful "OKs" come from...you're never too
old... ;-))

Does that last version fit your needs?

So in this script, when you remove line 23 and 33, you will still see OK.

That is being printed in loadproc. evaluate_retval will now always overwrite what loadproc has printed to the right hand side of the console.

We want to see any errors here :)

To make this clear to me:

First:
Line 23 contains 'evaluate_retval' after 'loadproc...vnstat'. This is
counterproductive, because...:

> That is being printed in loadproc. evaluate_retval will now always overwrite what loadproc has printed to the right hand side of the console.

Ok, understood. I'll delete line 23.

Second:
'evaluate_retval' in line 33 (umount_ramdisk ...) is similar with line
23. Here the output of evaluate_retval' would overwrite error messages
regarding the unmounting of the ramdisk.(?)

But: in this case I can't see where the [OK] should come from (see
above: "...you will still see OK") when I remove line 33, because I'll
see only the output of 'boot_msg'!?

Would be ok for me, I'll delete line 33, too - I'm just wondering.

> We want to see any errors here

Me, too. ;-)

Matthias
