perfsonar development work

[Błażej Pietrzak <>]

Hello all,

Since the official package naming policy has changed the old packages 
have to change their names.
The problem lies with package upgrading. If the name of the package 
changes the package management software does not remove the previous 
package.

In order to solve the problem for DEB packages one has to add two 
properties in the control file describing the package: "Conflicts" and 
"Replaces", both with the previous name of the package. So for example 
for "perfsonar-java-sshtelnet-mp" package one has to add:

Conflicts: ps-mdm-sshtelnet-mp
Replaces: ps-mdm-sshtelnet-mp

This will inform the package manager that it should remove the 
"ps-mdm-sshtelnet-mp" package from the system and then install 
"perfsonar-java-sshtelnet-mp" package.
If one would introduce only "Replaces" property then it will tell the 
package manager that the "perfsonar-java-sshtelnet-mp" package can 
override files of the "ps-mdm-sshtelnet-mp" package, so that is why one 
also has to add "Conflicts" property.

Unfortunately there is no such mechanism for the RPM packages. In case 
of RPM packages one has to create a dummy package with the previous name 
that has dependency for the package with new name.
