Not quite. This is how I'm thinking: if '-ep world' says virtual/pam |
| 65 |
needs to be installed, then it either |
| 66 |
* is in the world file, or |
| 67 |
* is in the system set, or |
| 68 |
* is a buildtime or runtime dependency (immediate or deep) of one of the |
| 69 |
packages in the world set (i.e., world file and system set combined). |
| 70 |
|
| 71 |
But it's neither in my world file, nor in my system set (checked with |
| 72 |
'emerge -epO system'). So it must be a dependency. Then why doesn't |
| 73 |
'-uDN --with-bdeps y world' demand it? Obviously, virtual/pam is listed |
| 74 |
as necessary for running or building something in my world set. '-uDN |
| 75 |
world' shouldn't omit merging something I need to run my packages. And |
| 76 |
with '--with-bdeps y' it also shouldn't omit merging something I might |
| 77 |
ever need to build these packages. |
| 78 |
|
| 79 |
The quoted equery call shows that virtual/pam is needed to run 7 pieces |
| 80 |
of software in my world. (I understand it's not literally needed for |
| 81 |
them to run, but that's the semantics of runtime deps and portage has |
| 82 |
no way to know the difference, I suppose.) And it's not an alternative |
| 83 |
to another possible dependency - it must be virtual/pam (checked some |
| 84 |
of the ebuilds). |
| 85 |
|
| 86 |
Even if it's all correct behavior, I'd still like to know where exactly |
| 87 |
is the robber on my train of thoughts. |

It seems that you assume that my current skype is a stable version. In |
| 151 |
fact, it isn't - see the quoted grep of the ebuilds. There is not a |
| 152 |
single stable version of skype in portage now. They're all ~arch. |
| 153 |
|
| 154 |
My ACCEPT_KEYWORDS="amd64". 'emerge skype' (I'll be omitting the |
| 155 |
'--autounmask y', it's the default anyway) wants to upgrade from my |
| 156 |
current 2.1.0.81 ~skype to 2.2.0.35-r1, which happens to be the latest |
| 157 |
available ~skype. I assume that's the strategy: if there's no stable |
| 158 |
version available, at least get the latest ~arch version. That's fine. |
| 159 |
But why doesn't the same strategy apply for a '-uDN world'? |
| 160 |
|
| 161 |
The manpage says nothing about this, as my eyes interepret it. There |
| 162 |
might be some unintended hidden behavior of --autounmask or --update or |
| 163 |
something else. If it's intended, I'd still like to understand the |
| 164 |
reasoning - just to get what's going on. |
