Attn Henrik: [hobbit] problem with CLASS definition (PATCH)]
Thus far I have gotten no acknowledgment that you are aware of this bug. I have a vested interest in seeing this patch be part of 4.3, as I have production servers utilizing this feature to handle automatic fail-overs.

Okay I came up with a workaround. The problem is that CONFIGCLASS gets reset to a default value (in hobbitclient.cfg). So, I created another variable, "CLASS". I then made a small mod to hobbitclient.sh that checks to see if CLASS got set to something, and if it did, it sets CONFIGCLASS to that value. Here are the changes:

I also just discovered that CONFIGCLASS gets converted to lowercase (which I should have seen plain as day in the sed command). However this is not the problem as the CONFIGCLASS in the client message is still using the default value of BBOSTYPE. I'm currently attempting to hack in a work around.

I did some poking around, and as far as I can tell, the problem is due to hobbitclient.cfg overriding the CONFIGCLASS variable. Here are some snippets from runclient.sh:
--class=*) CONFIGCLASS="`echo $1 | sed -e 's/--class=//' | tr '[A-Z]' '[a-z]'`"
export MACHINE MACHINEDOTS BBOSTYPE BBOSSCRIPT HOBBITCLIENTHOME CONFIGCLASS
hobbitclient.cfg contains this: ./hobbitclient.cfg:CONFIGCLASS="$BBOSTYPE" # Default configuration class for logfiles
hobbitclient.sh uses the CONFIGCLASS variable when sending the client message: ./bin/hobbitclient.sh:echo "client $MACHINE.$BBOSTYPE $CONFIGCLASS"
$MSGTMPFILE
Heres the actual client message header Im sending (not that CONFIGCLASS is being set to "linux" instead of the specified class: client host-app-23.linux linux

Anyone have any thoughts on this? I'm currently dead in the water without this working as it should. I tried emailing Henrik as well but I'm sure he is too busy to reply.

I have a host whose client was started via: "./runclient.sh --class=APP_PRIMARY start"
In the hobbit servers hobbit-clients.cfg, I have something similar to:
CLASS=APP_PRIMARY PROC "someproc" PROC "/some/other/proc" .... DEFAULT PROC sshd
The problem is that only the default proc "sshd" is being checked on the host. The expected behavior is that the CLASS would be used and other other procs checked instead. I know this has nothing to do with the DEFAULT setting, as using HOST=hostname works fine. I just cant get it to check the procs by CLASS. Is there any way to debug this? Shouldn't the CLASS show up in the "info" section? Do I need to put the class name in quotes on the command line?
