I'd call that critically dangerous in missing some changes. |
11 |
If I have a file in $FILESDIR, and change it, but it has the same name, |
12 |
there is no commit to the ebuild, and your .debs won't pick up changes |
13 |
at all. This is usually for cases with compile fixes that don't need |
14 |
revision bumps at all, but sometimes there are also changes to scripts. |

If you're making binary package .debs, I gather that you are grabbing |
17 |
the (pre|post)(inst|rm) and setup blocks for inclusion? |

That is an interesting use case, and would that would present a problem |
20 |
with any VCS migration. |

- Under SVN, you'd only have the global revision, which might not |
22 |
uniquely identify the file. |
23 |
- Bzr doesn't support keyword expansion in any released version. There |
24 |
are/were plans for it in 1.7, but I haven't seen anything since the |
25 |
first prototype. |
26 |
- Hg supports it with an extension: |

28 |
But has warnings about why it sucks |

See the 'keyword update intervals' item (mainly having to touch every |
31 |
file in the repo sometimes). |
32 |
- Git supports only the $Id$ keyword, and expands it to the SHA1 of the |
33 |
file, which ends up being a duplicate of the information we have in |
34 |
the Manifest. |
