Following on from the discussion of a few days ago concerning building Haiku on GNU/Linux without xattr support, I decided to move to a Haiku-hosted build. So the first step is to copy the haiku installation onto a BFS volume. In the command below, /Vault is a RO-mounted ext4 volume: /Home/mounty> tar cf - -C /Vault/mounty/haiku-x86 . | tar xf - which after running for about eight hours has hung and is sucking CPU. In particular, the reading process is taking ~98%. Is this interesting ? It's a bit vague for a bug report and I'm not sure if it's an ext4 problem or a tar problem. M.
