Ah, I see. I'm sorry, I wasn't thinking enough. Yeah, virtual/pam may |
| 22 |
be one of a list. But if nothing else, I have openssh and openssh says: |
| 23 |
RDEPEND="pam? ( virtual/pam ) |
| 24 |
No alternatives there. And I don't have virtual/pam, but do have |
| 25 |
openssh. So why does '-uDN world' not pull virtual/pam in? |
