I can certainly see the benefit here, but wouldn't that still result in (arguably) unnecessary (re)builds? If implemented well it'd also result in depcleaning them when they're later unneeded, too, so I guess it's a wash in that sense. Again, I'm not against it. In fact I'd probably use it, because some packages are really picky. I just don't know how well it would fit into the existing design at the code level. - -- Daniel Campbell - Gentoo Developer OpenPGP Key: 0x1EA055D6 @ hkp://keys.gnupg.net fpr: AE03 9064 AE00 053C 270C 1DE4 6F7A 9091 1EA0 55D6 -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAEBCAAGBQJWuegpAAoJEAEkDpRQOeFwoYIQALeAXnPOXzrC10AWplSt0K9D O3Mp8KpiMMUfIi1neM2LQAfW6Kp3lA9CaA547TdJ2ZXBJdTSfwPMe5rsWY2wqavD UvASgl4Ja4molsM3mQX3rYWbbzjZN38mZmYby26mPwyo8kAeXeqqIFDpPyG3F11M 0uT0lCg8W6q6qs00l02SZHmQKGQwCL4JLXNe9mj8WLcoaeMZjXwDCS3lhLz2L7at bveIm/yk5JaPSc3i8zcwmjDyoJ2fQg+1u2ujl+MzgVcxY8pfSnJN0q4CV06rC4xt 7F65OU8DhzaNr80UUfKCNdfVXwIlDNIEK1mz/tRe3Ad4bW1NW5DJFpm9xjpSPSlD Cse2GNBTxKYDi/mxlLBenCyqHta05TyzdqDODiOJRMzIXRf2jcPtOkg58tdUMl8D xw/qIFwcUeC44RfX9Kb9NkQcxuhyuLSPBcnGGdxeaUtJf92wpw4AINfSLj2B8nwv XyPan9bGku6gsG6C5oQ0JUsGdNu/qmukUieppE4yKbFgjzoIZcuOb18jKyDaxVKh QiQ9uI2xGvQYqAHVAraykAoBEl7EHISRRLn508VB8WZUxV39q5BwYtpYrxAJtSEY 60NuTTKmU7CXK4czHukrKPpkwkqNGIBgK1/m7dVpXjxcXfk/cdcwilv3EmO7f6fb XKundbhCB5ek42OGqTuG =+Yx3 -----END PGP SIGNATURE-----
