That one is either relatively simple, or I'm not understanding your |
8 |
question. |
9 |
|
10 |
Portage's installed package database, vdb, is located at /var/db/pkg/. |
11 |
It's organized as a category/package-version tree, much like the normal |
12 |
gentoo packages tree, except that the package dir names have the version |
13 |
appended (and of course there's no profile/metadata/etc subdirs). Most |
14 |
files in the individual pkg-ver dirs are plain text, tho the environment |
15 |
file is compressed (bz2 here, tho it's possible that's configurable, IDK). |
16 |
|
17 |
So a snapshot of vdb should be as simple as tarballing /var/db/pkg. You |
18 |
should then be able to untar it somewhere and do a recursive diff or |
19 |
whatever, to compare the freshly unarchived version against the existing |
20 |
one and get your list of added/updated packages based on the diff. |
21 |
|
22 |
The other question I didn't (as a user not a dev) understand. I'd need a |
23 |
fuller explanation (it feels like I came in half way thru the story and |
24 |
missed something critical, which has me wondering if I'm missing |
25 |
something on the first one too, since it seemed so simple, thus the |
26 |
remark above to that effect), but it's possible a dev will understand |
27 |
better and be able to answer. |
