Answered my own question... here's what I came up with in case anyone else
wants the answer:
FILESYSTEMS=`ssh -q [EMAIL PROTECTED] df -l|awk '/\// {print $NF}'|tr '\n' ''`
rsync -av -e 'ssh -q' --one-file-system --numeric-ids --relative \
--delete [EMAIL PROTECTED]:"${FILESYSTEMS}" /backups/$SRCHOST
I used tr to translate the carriage return from the df output into a
space. Then I used double quotes around the $FILESYSTEMS variable on the
rsync line so that the variable could be interpreted but the value still
quoted.
If there are any better ways to do this, I'm still all ears.
