What data are you using for the "Conflicts are rare" statement? |
| 10 |
Using |
| 11 |
http://http.us.debian.org/debian/dists/testing/main/binary-i386/Packages |
| 12 |
I get: |
| 13 |
|
| 14 |
[jnelson@agamemnon jnelson]$ grep "Package: " Packages | wc -l |
| 15 |
6669 |
| 16 |
[jnelson@agamemnon jnelson]$ grep "Conflicts: " Packages | wc -l |
| 17 |
1637 |
| 18 |
[jnelson@agamemnon jnelson]$ grep "Replaces: " Packages | wc -l |
| 19 |
1265 |
| 20 |
[jnelson@agamemnon jnelson]$ grep "Provides: " Packages | wc -l |
| 21 |
923 |

So roughly 25% of the packages in Debian have a Conflicts line, |
| 36 |
and ~20 percent have a Replaces line (afaik, replaces is for |
| 37 |
when a package changes names). Provides is for meta packages, |
| 38 |
and is present in roughly 14% of the packages. |
| 39 |
|
| 40 |
25% is certainly not "pretty rare". |
| 41 |
|
| 42 |
An example from Debian: |
| 43 |
|
| 44 |
Replaces: cdgrab |
| 45 |
Provides: cdgrab |
| 46 |
Depends: cd-discid, wget, cdparanoia | cdda2wav, vorbis-tools (>= |
| 47 |
1.0beta4-1) |
| 48 |
Suggests: eject, distmp3, id3 (>= 0.12), id3v2 |
| 49 |
Conflicts: cdgrab |
| 50 |
|
| 51 |
Yikes! All of that is useful, however. |
| 52 |
|
| 53 |
As I understand it, gentoo has 'meta' packages as well. Debian |
| 54 |
uses these to great effect, but I've always been bothered |
| 55 |
by the naming scheme -- perhaps 'meta-c-compiler' vs. 'gcc', and |
| 56 |
'meta-httpd' vs. 'httpd' or some specific httpd would be better. |
