Not sure if this helps, but I have subvolid=0, which contains all my
subvolumes, mounted under /.root/
/etc/fstab:
LABEL=panda / btrfs subvol=rootvolume,space_cache,inode_cache,compress=lzo,ssd 0 0
LABEL=panda /home btrfs subvol=home 0 0
LABEL=panda /root btrfs subvol=root 0 0
LABEL=panda /var btrfs subvol=var 0 0
LABEL=panda /holding btrfs subvol=.holding 0 0
LABEL=panda /.root btrfs subvolid=0 0 0
LABEL=panda /.backupadmin btrfs subvol=backupadmin 0 0
/Varlib /var/lib none bind 0 0
panda:~# ls -l /.root/
total 0
drwxr-xr-x. 1 root root 580800 Jan 30 17:46 backupadmin
drwxr-xr-x. 1 root root 24 Mar 27 2012 home
drwx------. 1 root root 742 Mar 19 15:50 root
drwxr-xr-x. 1 root root 226 May 16 2012 rootvolume
drwxr-xr-x. 1 root root 96 Apr 3 2012 var
In my snapshots script:
...
yyyymmddhhmm=`date +%Y%m%d_%H.%M`
...
for subvolume in `ls /.root/`
do
...
/sbin/btrfs subvolume snapshot ${filesystem}/${subvolume}/ \
/.root/.snapshot_${yyyymmddhhmm}_${hostname}_${subvolume}/ || result=2
...
done
...
This creates timestamped snapshots for all subvolumes.
