bind depend

rshadow · #1 27th May 2006, 07:36 AM

Hello everybody,

I'm really new to Fedora, however I've been using Linux for awhile. My question is why is bind a dependencies for a crap load of network apps? There shouldn't be one single reason why I have to have bind installed on my machine. I don't wan't it, however if I try to remove it, I will lose alot of packages that I do need. If I wan't a DNS server I will install it myself, and choose the dns server I wan't (namely djbdns).

So... how can I remove bind as a dependency for alot of other network applications?

rpm has a --nodeps option

Ok... how would I go about removing bind from my machine with yum? If I manualy delete it I can forsee alot of trouble.

yum remove packagename

Use system-config-securitylevel, also known as the Security Level Configuration graphical tool, to control the Boolean values of specific daemons. For example, if you need to disable SELinux for Apache to run correctly in your environment, you can disable the value in system-config-securitylevel. This change disables the transition to the policy defined in apache.te, allowing httpd to remain under regular Linux DAC security.

I guess I should have "volenteered a little more info, that being "I have no idea what will happen if you remove bind even
without removing everything that depends on it (or that it depends on)" . I don't know anything about it but it sounded like
you did, (and I'm sure you do) and you knew you could do without bind and wanted to dump it without dumping
everything else that wanted to be dumped with it.

I'm not so sure you can remove it with yum since that is yums job, to add and remove packages while resolving
dependencies. I have not seen a nodeps option in yum. I have seen yum do just the opposite though. It has
installed many dependencies for one package, and when I removed that package it did not remove the dependencies it
installed with it. I guess it's still not quite "smart enough"

Sorry I don't have an answer for you, but I do have a question (always curious) What kind of problems do
you forsee with rpm -e --nodeps?

as mentioned previously, this command will also remove about 45 other programs as well, because I'm assuming that it thinks these programs depend on bind being installed.

Yes, I have removed bind from running, but I don't wan't it on my machine. I will never run bind. I don't wan't the service being started accidently by whatever chances. As I mentioned if I want a DNS service I will use (the intensely more secure, understandable, and easy) djbdns.

Well the only problem that I can forsee is that Yum will still think that bind is installed. Later this could cause a variatey of problems and headaches. And as far as the software being removed, none of it should depend on bind. Unless bind delivers some sort of service other than DNS services. I don't understand why anacron would require it, nor NetworkManager. I can see how both services might make *use* of it, but under not cirucumstances should it require it.

This is why I have always stuck with Gentoo (I love being able to install what I want.) , but I'm really trying here people.. really honest I am. I guess i'm just too dumb with a normal distro to use it effectively.

Don't sound dumb to me.
As for yum not knowing bind is gone, I'm not so sure that is true. Yum does use (an) RPM db. I don't know if it's "THE"
RPM db or if it uses one of it's own. Never really checked. Maybe someone else will come up with an answer to that.

if u use nodeps for unistalling it remove the files which may be required by another package

I think yum will not list the package if u unistall using rpm -e option

No, yum is a front-end to the RPM packaging system, and it will see that the package has been removed and dependencies broken. Most likely it will simply re-install bind the next time you install or update anything, alterenatively it will stop working.

If you really think the dependencies are in error, you should file a report in Bugzilla.

Anacron doesn't require bind (try "yum deplist anacron"). NetworkManger requires caching-nameserver, and that in turn requires bind.
