Why not simply do:
| Code: | | qpkg -I -nc > /var/cache/edb/world |
and then update world

I'd be a bit leery of doing this, myself. After hunting around in Bugzilla, I came across This comment (comment number 4, in case the anchors don't show correctly). It seems that if you put ALL your installed packages in the world file, you might end up upgrading a library which will break compatibility with something that depends on it. Not that I've seen that happen, or anything, but it might be something to think about before doing it. |

Just curious, how would installing/upgrading a package break something that depends on it? I mean, your not removing the package, your upgrading it?
Although, my preference is to do "qpkg -nc -I | xargs emerge -u" to update world. I've done this almost exclusively, and it has worked great. |

I agree that it really shouldn't happen, but I'm sure that it does. Let's say libfoo gets upgraded from 2.4 to 2.5. This upgrade breaks compatibility, so it really should have been called 2.5, but wasn't. So you emerge 2.5, and you get a /usr/lib/libfoo.so.2.5, which symlinks itself to /usr/lib/libfoo.so.2, which symlinks itself to /usr/lib/libfoo.so. Now, you *do* still have /usr/lib/libfoo.so.2.4, but anything that's linked to just "libfoo" or even "libfoo v2" is going to pick up the new version, which is going to break your programs. Alternatively, let's say it's numbered correctly, and the new version comes out as "libfoo 3.0" instead. Well, if the ebuilds aren't set up properly, when you do an "emerge clean" on your system after installing the new ebuild, you'll end up wiping away your old versions, too. I imagine that "emerge clean" is fairly common after an "emerge --update world."
Now, admittedly, these kind of problems typically extend from authors using poor naming conventions and misnumbering version releases, but there are many points along the process where things could fail.
I could be wrong, of course, but that's how I see it.
[nitpick]Also, it's "you're," not "your." :)[/nitpick] |

What happens when for an exmpale openssl is upgraded due to a security issue (assuming you've missed the GLSA)
In that case update world won't pick this up, if all the packages where in the world file, it'd be upgraded.
I know that some packages can be broken, but that's where common sense kicks in (e.g: I haven't upgraded ogg yet as it'd break various apps).
There are pros and cons for both arguments, it is up to the user to choose (like everything else in Gentoo  ).

If you are looking for a one-time update rather than fixing up your world file temporarily/permanently, you can do:
| Code: |
emerge -pu `qpkg -I -nc`

that does the same thing as "qpkg -nc -I | xargs emerge -up"
Just a different syntax. |

I agree with everything you're saying, and it does deal alot with the author of the package (not the ebuild) versus anything else.

This isn't slashdot.. it's not becoming to point out trivial issues in someones post just to make yourself sound smarter.

Ach, then please accept my apology in this matter. I've always been a stickler for grammar, and once I was away from a computer I realized I probably shouldn't have brought it up. I shan't make the mistake again. /me bows |

Oops, I missed your suggestion that preceded my post in the thread! Obviously they are equivalent.
PS. emerge -pu world seems to have changed its behavior at some point in time. The man page used to mention that a "-u world" updated all dependencies of world packages. Now it explicitly says it doesn't

OH wonderful...
I wonder if this is because they are working on something dedicated to dependancy updating, or if there are just issues? |

| well.... I think it's somekind of "philosophie" or name it "base for features" ... if in the world-file are just the apps U want, then the systems knows that and dosn't bother you with silly things.... also if a dep is no longer needed (due USE modifications) the system knows "I just needed the package bcos of a dep and not bcos the user wanted it" - so in case you change your mind and want to compile all apps without sasl, the system would remove sasl as soon as no package needs it anymore.... |

I got an updatepretend bash script, and a updatesystem script.
something like this:
#!/bin/bash
cd /var/cache/edb
mv world world.real
qpkg -I -nc > world
emerge -pu world
mv world.real world
with and without -p |

You should know how much it wants to rebuild (you know the yellow R - not update) over here!!! It looks like too much
