Indeed. But that's why yum / dnf displays you the whole transaction and asks you to *confirm*. For me it is a totally reasonable and sane approach. If you claim there are people who won't read the list of to-be-removed packages and blindly hit *Y* - well, I belive you are right - there are such people. But we won't stop them from hurting themselves, sooner or later. If you think the 'confirmation required' dialog is not enough - please create a plugin for dnf, and make a feature request for its inclusion. Then at least the discussion is productive. > > the same applies to "rm -rf /" which is also protected and > can be overriden with a CLI switch - for the same reason: > it's hardly what the user really wanted to do Exactly. System warns you, but if you insist, it will allow you to "rm -rf /". The same is with dnf. It will show you the list of packages it's going to remove, and ask you if you are sure this is what you want. What more do we need? I hate when my OS tries to be smarten than me. So, if the command "dnf remove kernel" would immediately remove all the kernels without asking for confirmation, I'd say you're right. But it's not. And you are wrong. Thanks. Bye! -- jaroslav
