Using the data you provided on the GitHub issue we've been able to run a few tests and I can confirm
che-mount works. However, due to the size of the workspace it's trying to synchronize, the process hasn't finished after an hour in our test environment. In other words, the
unison process running inside the
che-mount container is working but because it doesn't print any output message, it appears to be frozen, despite still doing work in the background.
Although we didn't complete the test, the synchronization should finish eventually.
Hope it help.
