sosetup -w not writing answer file correctly in some cases

[dougburks]

From Steve Baker:

I've been debugging sosetup a bit with answer files and it looks like sosetup -w writes out SNIFFING_INTERFACES space delimited like this
SNIFFING_INTERFACES=ens19 ens20 ens21
but running sosetup with said answer file fails because it needs comma delimited
when it reads it back in
source "$ANSWERFILE"
       # copy SNIFFING_INTERFACES into INTERFACES
       INTERFACES="$SNIFFING_INTERFACES"
with the space delimted sourcing the answer file actually produces an error right away

line 12: ens20: command not found

from what I can tell this line should be added to sosetup in the section where the answer file is written out
echo "FORWARD=$FORWARD" >> $WRITEANSWERFILE
without FORWARD set sosetup doesn't setup the local port forward in AutoSSH options

and syslog doesn't get to the master
