```
$ mount | grep overlay
/cow on / type overlay (rw,relatime,lowerdir=/filesystem.squashfs,upperdir=/cow/upper,workdir=/cow/work,uuid=on,xino=off,nouserxattr)

```
Also, in case it helps, I run this script upon booting the live cd image:
```
$ cat thunder2.sh
cp -R /media/lubuntu/drive/startup/thunderbird /home/lubuntu/snap/thunderbird/common/.thunderbird
cp /media/lubuntu/drive/startup/lubuntu_thunder/profiles.ini /home/lubuntu/snap/thunderbird/common/.thunderbird/
```
Previously I was running thunder.sh (this below worked in all prior Lubuntu versions):

But with the conversion of thunderbird into snap only, I had to change the directories.
