search local home for the username being used remotely (0xdiag) for validating the path name you're going to use when running remotely. means local wants to mimic remote setup, but you always want that anyhow. if not found, still looks for other places, so a remote ln -s always be created manually (once) to match the local setup if necessary, to make things work. (assuming it's found somewhere locally)
Merge branch 'master' of github.com:0xdata/h2o
useful to keep username in local node state to match remote case
works
good to know if we're executing remote, optional H2O_REMOTE_BUCKETS_ROOT env. var.
