I have a blocking related issue here:

I am a littel bit afraid just to remove device-mapper, isn´t it an important system component? What is the best procedure here? Thanks a lot ..

I believe that new udev version 'deprecates' device-mapper. Here - look:

Code:
$ emerge --search device-mapper udev

[ Results for search key : device-mapper ]

It *should* be fine to remove it. Just don't reboot before emerging udev. :wink:

Thanks, what would happen if I reboot anyway? Is my system borked then? Just for understanding ..

I'm 99.9% sure it wouldn't be borked, but I'm not exactly sure what would happen. I imagine gentoo wouldn't boot and you'd have to use portage via a livecd to finish your emerge.

If this is a work system then don't take my advice. I'm just telling you what I would feel fine doing.

...Actually, I would feel fine doing this on my work box as well.

hi all!

i had the same problem. my solution was to unmerge device-mapper, then emerge the packets left, and then emerge lvm2 instead of device-mapper (device-mapper is blocked by the newly installed udev package).
the only thing i wonder is, why device-mapper package is still under development if it is merged into lvm2...

Maybe this is a stupid question but anyway ..

I just read that the device mapper is managing multiple disk volumes. If I dont have such a thing like raid volumes or similar, but just a single harddisk. For what purpose do I need device-mapper or lvm2?

I know I never installed such a think manually so it came into my system by dependencies, therefore i assumed it is an essential component without my system wouldn´t boot anymore. Is this the case or can I just remove and forget it?

thanks
Erdie

The big thing that has hit me with this is that my wireless card is no longer working. I'll dig around and see if it has something to do with NetworkManager

I just removed device-mapper and restarted the world update. I works. Thank you all for your advice.
