Bugzilla Bug 142604

net-print/hplip-1.6.6a shouldn't depend on sys-apps/hotplug because
sys-fs/udev-096-r1 has hotplug functionality built in and seems to have
conflicts with sys-apps/hotplug.

Hints for the conflicts can be found here in bugzilla and in the forums.
Unfortunately I don't have a link right now. But I had some issues with my usb
scanner, the /dev/cdrom and /dev/dvd links and udev rules which have been
ignored by udev. After unmerging hotplug everything is working well again as
before I'd upgraded to the first udev version with hotplug and coldplug
functionality, before udev-089 I guess.

So it's not really useful if hotplug is installed automatically again because
of the hplip dependency.

Maybe there are other packages which depend on hotplug. They are of course also
affected and should be changed correspondingly.

Maybe there could be made a virtual/hotplug on which these packages could
depend and virtual/hotplug is inherited by hotplug as well as the newer udev
versions.

I don't know what the hotplug dependency is for but maybe it's sufficient if
hplip depended on sys-apps/hotplug-base instead of sys-apps/hotplug because
sys-apps/hotplug-base is a dependecy of sys-apps/hotplug as well as
sys-fs/udev.

no idea if hotplug is actually needed, I rather guess not.

I anged it to hotplug-base because that is installed anyway and should not
break anything.

Thanks for the bug.

AFAIK, as of February 2007 udev completely replaces all hotplug functionality,
hotplug is being phased out and so the dependency should be removed entirely.

Also, there is an "after hotplug" statement in /etc/init.d/hplip which should
be pretty useless now, since hotplug isn't installed any longer.

On my system, hplip is the only package still pulling in hotplug-base.
