This is a direct re= sult of its Linux-only origins. OSXFuse extended the protocol to add those feat= ures (and others), but they had to fork libfuse to do it. FreeBSD has thus far = had a policy of no changes to libfuse. Even if we were to abandon that policy,= we can't add chflags and st_birthtime support without bumping the FUSE kernel = API version past the most recently published version in libfuse. The reason is because libfuse includes its own copy of the kernel API header. Changing t= he FUSE protocol without reving the kernel API past what is already published = by libfuse would thus break existing binaries. Attached is a patch that adds st_birthtime support to fusefs(5). However, = it adds it at protocol version 7.9, so it breaks compatibility with existing binaries. The patch also includes some OSX definitions. I thought that including them would make it easier to update libfuse. --=20 You are receiving this mail because: You are the assignee for the bug.=
