 Hi, we at Gentoo/FreeBSD just ran into this issue with a script that had
 worked on Linux, since it expected EEXIST for all dirs (it did not
 expect EISDIR when trying to mkdir an existing dir when it hit "/").  We
 have fixed it, but since the mkdir/rmdir man pages do not specify EISDIR
 as a potential error code - and just for correctness/compatibility
 reasons - my feeling is that it would be good to fix this issue.  I also
 have no experience hacking FreeBSD kernel or userland utilities, so I
 have not pursued providing a patch.  Sorry if this follow-up is not
 useful without having a patch.
