yum install too many packages

[Leo Liu]

Hi there,

I use CFE3.6.2 and have this promise on centos7 (with EPEL enabled):

packages:
"collectd"
package_policy => "add",
package_method => yum;

but it installs 31 packages starts with collectd.

I tried yum install -y collectd in shell and it only installs one
package.

A bug?

Thanks,
Leo

There is no easy fix at the promise level, but the `package_latest`
bundle will do what you need:

https://docs.cfengine.com/docs/master/reference-standard-library-packages.html#package_latest

Thanks, that seems to solve the issue. it is using the
yum_rpm_permissive package_method, the doc of which doesn't explain the
meaning of permissive. What is `permissive' in this context?

Thanks,
Leo

Normally you have to specify the package version, and it defaults to
"*", which then triggers the bug of installing "xyz-abc" when you ask
for "xyz".

The "permissive" bodies set

package_name_convention => "$(name)";

which is permissive in the sense of not requiring the version. I
couldn't think of a better name at the time I wrote them, sorry :)

Thanks for the explanation.

While browsing the stdlib I noticed the two methods and my guess of
their meanings is opposite to what you have described i.e.
yum_rpm_permissive would install everything related to a package.

Could you add a bit of documentation to the functions so that their
difference is easier to see?

Thanks,
Leo

Yeah, sorry about that. I should have called it `yum_rpm_1` :)

The masterfiles.git maintainers (I'm not one anymore; Nick could do it
maybe?) should do that, renaming the bodies if they see fit. My previous
note may be helpful.

Yes indeed, thanks Ted.
