This algorithm better matches what I meant in my earlier posting, so +1 from me. (And if anyone has an ACCEPT_KEYWORDS value of "~amd64 - -amd64", they deserve any issues that may arise). The only issue I have with it is that EFFECTIVE_KEYWORDS should be expanded to contain "*" if any stable keyword is present and "~*" if any unstable keyword is present (or "*" and "~*" in ACCEPT_KEYWORDS should be pre-expanded). - -- Jonathan Callen -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.19 (GNU/Linux) Comment: Using GnuPG with Mozilla - iQIcBAEBCgAGBQJPmvKPAAoJELHSF2kinlg43ZgP/1F++FzGzmUZxy+2enHeCIRb 47y4hFxZG18ulWijr0qEJTizDGCxE8RCBfanM4I1G4qSdy0Eyg+6yIdT+B1FRZ1F Wp5p/CPPX/AfxgJ+LTTmY5V3f8AWrk1MfX4sGoy+0DGzgMB+Z87M6f10wAWcLIV5 RHd3591kyL5AOifaaM53/tgFcjvXECz+DfbDaVFaD1XjnSkEsu6aV6k1xaVqGGfF pK3Dqo672XUKR1laFODYEkknO0JlR8EcU8De4pkdgj8ffbf0g2uVXbpTCEgd+w4I 0eEd+LNVDAnTQntMuSETK5ysfYIVOPOmo1KoaR5XSFVsNL8UzjUKY1Yx7owXrm+N 2OR+2JtdCnjkTveZZbP/Y8M74wiZeptOsgK5PxN+C/3vLWJ0LMrxIsWMugc0Oihv 3ddk1/WQolBtA8+DDBY+mOrJuKa5R7eqLAJQVmFLyDVLGu2dTCO26TaT7IKWnN8J Kw0RqscOFd93RcsfpgKwM2ij+8N+QlGgvK4qBwR9MAIEEQAPtx5Rxi6dxly/b/7h 6jC2Yt8UqVOCloQ4vjoopIqA7QYGk3JS+yp27HAVR+cXDX1OWntEU+LeVlmm27k9 vuEBRXosD9DpYCQ7OCQOzYa5TefgVs76TY/ygSgpkHlzcCbZ5iRwholKuOuKSvyd mRi9g8/nctJXFkHn17GV =LYAv -----END PGP SIGNATURE-----
