sys-apps/hotplug-20040923-r2 produces the following installation message:
* If you still have the file /etc/hotplug/isapnp.rc on your system,
* please delete it by hand, the file /etc/hotplug/pnp.rc superseeds it.
However, this file is actually installed by hotplug:
# equery belongs /etc/hotplug/isapnp.rc
[ Searching for file(s) /etc/hotplug/isapnp.rc in *... ]
Deleting the file, then re-emerging hotplug causes it to be recreated.
If the message is correct, hotplug shouldn't create this file; if it isn't correct, the message should be removed or amended.
Heh, good catch. The file now contains nothing, but we don't realize it...
sys-apps/hotplug is useless with any recent udev version, and 2.4 kernels are no longer supported. Unmerge it and move on.
