[Spacewalk-list] Excluding Packages in a Channel?

[Wojtak, Greg]

Is there a way to exclude certain packages in a channel from being installed/updated unless overridden?

For example, I built a php-5.3.5 set of packages and I pushed them into a custom channel.  All of my systems are currently subscribed to this channel, but there are couple systems where it would be undesirable to update to php 5.3.5.

Is there an equivalent way to exclude packages by default within a channel (similar to adding the excludepackages line to a repository config file with yum)?  I'd hate to have to create separate channels with two or three packages in them each.

Thanks in advance!
