What works(or at least worked last time i checked):
- using shellinabox
- launching pwra from shell and looking at it over vnc (i used tigervnc)
- launching runtime with a simple plc program (it also starts Status Server which is checked with a promise)
Bugs to fix:
- [test result] While passing tests ok on slapos-sr-testing inside Webrunner, remote testnodes suffer from what looks like a sudden directory disappearance:

Junk to clean:
- debugging stuff.
- (possibly) LD_LIBRARY_PATH from shellinabox session (it should be no longer needed)
- commits about altering python rpaths (it is no longer needed because a proper order of pycurl loading was restored)
Possible improvements (without altering functionality):
- switch to gtk to improve compilation times (last time this path was blocked by a proview build bug but that may be fixable) since qgtkstyle of qt still uses gtk
- switch from oatchelf to chrpath to depend on gcc less
- find a way to turn off doxygen documentation generation to turn gcc dependency off entirely and remove the second after qt compilation timesink
- ability to download an arbitrary proview-r plc package.
Future directions (with altering functionality):
- fully headless build without any graphical dependencies.
- simulators of modbus-tcp devices for tests.
