Hello All,
I'm a bit of newbie with rpm/yum, seeking the help from rpm/yum experts.
Suppose I have an RPM package A which depends on package B. RPM A's spec has 'Requires:B' tag with 'autoprov' and 'autoreq' enabled.
When I install RPM A on a 'centos 6.5' machine with 'RPM version 4.8.0', using the command `yum install A` :
- `rpm` installs A first, then it installs B.
- The installation of B could partially fail. That is, A would installed
even if the installation of the dependency, B has failed.
Is this the expected behaviour? (Shouldn't B be installed before A?)
AFAIK yum performs installs and updates as atomic operations, ie in your case if installing B fails yum will also roll back the install of A. Doesn't it?
Can the same behaviour be expected across versions (such as el5)?
I was hoping that the dependencies would be installed before the main package is installed. Which would prevent the installation of the main package, If one of the dependencies failed to install.
I have tried `PreReq` tag as well, which has same behaviour as far as I can tell.
Is there any other means to accomplish my requirement?
