not dangerous. only you need to look carefully at what depclean wants to delete. |
| 2 |
as gentoo says, in some cases it could break dependencies needed by other software and |
| 3 |
to avoid damage you should run revdep-rebuild, which scans all dependecies and reinstalls |
| 4 |
them if it finds something is missing. |
| 5 |
I use both regularly, especially after an emerge --update world and never had any real |
| 6 |
trouble with it. |

|
| 8 |
hope this eases your concerns a bit |

Yes. I think it is also mentioned in the gentoo handbook. In fact, you |
| 70 |
should not use --unmerge because it doesn't check dependencies before |
| 71 |
removing the package. |
| 72 |
|
| 73 |
If you want to delete a package only if no other package depends on it, |
| 74 |
either remove it from world or use |
| 75 |
`emerge -av --depclean <package_name>`. |
| 76 |
The latter has the advantage of also telling you what depends on it. |
