dockertest::build() fails: Could not find package root

[marcianito]

I have a simple problem: After following instructions to start using this tempting project in order to test my R-package, I created the "docker"-folder within my R-package root dir (as suggested), started R from within this folder and run dockertest::build(). The image building fails, giving back the following message:

dockertest::build() Klone nach 'self' ... Fertig. Fetching DESCRIPTION for traitecoevo/callr Fetching DESCRIPTION for traitecoevo/dockertest Fehler: Could not find package root. Zusätzlich: Warnmeldungen: 1: In file.rename(dest_tmp, dest) : kann Datei '/tmp/RtmpsinGHy/file295f5c839d51' nicht in '/home/mreich/.cache/dockertest/github/traitecoevo/callr/DESCRIPTION' umbenennen. Grund 'Ungültiger Link über Gerätegrenzen hinweg' 2: In file.rename(dest_tmp, dest) : kann Datei '/tmp/RtmpsinGHy/file295f1ea9a1e2' nicht in '/home/mreich/.cache/dockertest/github/traitecoevo/dockertest/DESCRIPTION' umbenennen. Grund 'Ungültiger Link über Gerätegrenzen hinweg'

I have no idea what could be the reason. I run R with and without sudo (thinking this might be a rights issue) but both resulting in the same error. Can anyone point me to a solution? That would be great as I would really much like to use this package!

This was an experiment that I have been meaning to resurrect as I'm back using docker more. In the intervening time, docker has massively changed and some packages have appeared on CRAN which clash with the internal names that we have been using (e.g., callr).

There was another attempt at doing this sort of thing using Gabor's sysreqsdb but I can't find the link right now!
