This is based on #13 and is mostly a proof-of-concept to show how
partialLookupInRootcan be adapted to implementSecureJoin.Note that due to the different semantics, there are test failures when dealing with dangling symlinks. I'm not quite sure what we should do for those (emulating them using
partialLookupInRootwould get quite expensive -- especially when usingopenat2). And obviously we can only switch the implementation on Linux becausepartialLookupInRootis Linux-only.
