| 26 | * Known difference between busybox dpkg and the official dpkg that i dont |
| 27 | * consider important, its worth keeping a note of differences anyway, just to |
| 28 | * make it easier to maintain. |
| 29 | * - The first value for the Confflile: field isnt placed on a new line. |
| 30 | * - The <package>.control file is extracted and kept in the info dir. |
| 31 | * - When installing a package the Status: field is placed at the end of the |
| 32 | * section, rather than just after the Package: field. |
| 33 | * - Packages with previously unknown status are inserted at the begining of |
| 34 | * the status file |
