\featurelabel{mtime-preserve} |
| 69 |
In EAPIs listed in table~\ref{tab:mtime-preserve}, the package manager |
| 70 |
must preserve modification times of regular files. This includes files |
| 71 |
being compressed before merging. Exceptions to this are files newly |
| 72 |
created by the package manager and binary object files being stripped |
| 73 |
of symbols. |
| 74 |
|
| 75 |
When preserving, the seconds part of every regular file's mtime must |
| 76 |
be preserved exactly. The sub-second part must either be set to zero, |
| 77 |
or set to the greatest value supported by the operating system and |
| 78 |
filesystem that is not greater than the original time. |
| 79 |
|
| 80 |
For any given destination filesystem, the package manager must ensure |
| 81 |
that there are no two preserved files $a$, $b$ in that filesystem such |
| 82 |
that the comparison $\mbox{mtime}(a) \leq \mbox{mtime}(b)$ does not |
| 83 |
give the same result as the same comparison would have given under the |
| 84 |
original image directory. |
| 85 |
|
| 86 |
In other EAPIs, the behaviour with respect to file modification times |
| 87 |
is undefined. |
