Hello everyone,
I''m just getting to grips with Puppet so apologies if I''ve
missed something.
I''m wondering if there is a way to require that something
isn''t the case.
My current situation/example is that I''m trying to uninstall one
package ("mysql") and install another one that conflicts with it
("MySQL-client-community") in one puppet run.
I can do something like:
package { [ "mysql" ] : ensure => absent, }
package { [ "MySQL-client-community", ] : ensure => installed, }
Which is fine, unless "MySQL-client-community" is scheduled to be
installed before mysql is removed, in which case it errors and I''m
left with a system with no mysql.
Obviously, I can just run puppet again and it''ll be fine but
I''d
really like to do something like:
package { [ "MySQL-client-community", ] : ensure => installed,
require => ! Package[ "mysql" ] }
with the ! negating the requirement.
Is this possible or am I approaching this from the wrong angle and I
should be doing something quite different?
Thanks,
Tim

I''ll work find if you remove the "!". That will require resource not the package itself and the resource says to remove the package. -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.

Hi Tim,
What you want is this:
package { "mysql": ensure => absent, before =>
Package["MySQL-client-community"]; }
package { "MySQL-client-community": ensure => installed;}

package { "MySQL-client-community" : ensure => installed, require
=>
Package[ "mysql" ] }
will just work, as you are requiring the the mysql package is already absent
before you install the other package.
