Our /tmp directory is too small and I don't have access to increase it currently. We need to change the default tmp directory from /tmp to /app.

What do you mean by "large"? I currently have 25 sessions lying around
in /tmp and they are 14MB in total. The largest one is 6.4MB.  Is that
really a problem?

We had a bug a while ago where /tmp/.x2go-username/C-*/session.log
grew to some GB (see
https://www.mail-archive.com/x2go-user@lists.x2go.org/msg04107.html)
but this is fixed in the current release nx-libs 3.5.99.26.
