Trying "yum info yum-plugin-ps" we get:
When this plugin is installed it adds the yum command "ps",
which allows you to see which running processes are accociated
with which packages (and if they need rebooting, or have
updates, etc.)
Ignoring the glaring spelling error, this seems to imply that it also
detects packages which have been updated and would affect running
processes (rather like needs-restarting).
"yum ps" on its own appears to do nothing. A look at the source
indicates that for a complete listing you need to do "yum ps all" (as
root of course), while "yum ps foo\*" restricts output to packages (or
is it processes?) starting with "foo". However as far as I can see this
doesn't work. IOW not only is there no usable documentation, but the
source comments are wrong.
This stuff really needs to be documented. Same goes for
needs-restarting.
