It is, but far less dangerous than --unmerge. depclean will only remove |
| 29 |
packages when portage /thinks/ it is safe. unmerge will always remove |
| 30 |
them, even if it breaks the system. Nevertheless, like Dale said, you |
| 31 |
should be careful with depclean and use -a or -p with it. But if |
| 32 |
depclean makes an error, there is usually something else wrong with your |
| 33 |
system. |
