Public bug reported:

This is a tracking bug for what might be kernel bugs or kernel
configuration changes.

As described [1], memory used by simply mounting a squashfs file (even
an empty one) is ranging from almost nothing (on certain distributions)
to 131MB on Ubuntu 16.04 and 16.10 on a single-core machine or VM.

The amount is excessive and should be investigated by the kernel team.
We may need to change the kernel or at least the configuration we ship
in our packages and kernel snaps.
