## TIPS & TRICKS
### Adding a DwarFS image to /etc/fstab
This should be relatively straightforward if you're already familiar
with adding other FUSE file systems to `/etc/fstab`. An entry looks
like this:
dwarfs#/path/to/image.dwarfs /mnt/mountpoint fuse noauto,defaults,user,cachesize=1g 0 0
The first bit before the `#` tells `mount` to look for `mount.dwarfs`,
which is installed as a symbolic link to the DwarFS FUSE driver. The
part after the `#` looks pretty much like any other `fstab` entry.
It starts with the path of the file system image to mount, followed
by the mount point, followed by the file system type (`fuse`), and
finally followed by a set of options.
If you want to automatically mount a DwarFS file system, you'll also
need the `allow_other` option to make sure non-privileged users will
be able to access the data. If you want to work with overlays, you'll

to work, you will have to set `user_allow_other` in `/etc/fuse.conf`.
### Setting up a writable file system on top of a DwarFS image
This will show you how to set up a read/write layer on top of a
