Hi all, Commit 3211e8e9c0565fae8b13ba0115e3a23ad3ae8ade added error checking to a mkdir("/etc", ...) call in pwdgrp_init().
That call might fail if the directory already exists. In my case, because I'm tarfs-ing stuff into /etc before invoking the NFS client, which calls pwdgrp_init(). The attached patch allows the mkdir() call to fail with EEXIST.
