I am getting a blockage involving device mapper

[ebuild     U ]  sys-libs/e2fsprogs-libs-1.41.9 [1.41.3-r1] USE="nls" 485 kB [0]
[blocks B     ]  <sys-fs/e2fsprogs-1.41.8 ("<sys-fs/e2fsprogs-1.41.8" is blocking sys-libs/e2fsprogs-libs-1.41.9, sys-apps/util-linux-2.16.1)
[blocks B     ]  <sys-libs/e2fsprogs-libs-1.41.8 ("<sys-libs/e2fsprogs-libs-1.41.8" is blocking sys-apps/util-linux-2.16.1)
[blocks B     ] sys-fs/device-mapper ("sys-fs/device-mapper" is blocking sys-fs/udev-146-r1)

I looked on bgo and found posts today involving this.  They were
"resolved" by noting "device-mapper was merged upstream into lvm2.
Emerge a recent lvm2, it will automatically
unmerge old device-mapper."

I am not running lvm2 on this machine.  I have device mapper because

  sys-fs/cryptsetup-1.0.6-r2 pulled in by:
    sys-apps/hal-0.5.12_rc1-r8

  sys-fs/device-mapper-1.02.24-r1 pulled in by:
    sys-fs/cryptsetup-1.0.6-r2

Does this mean I should emerge lvm2 even though this machine does not
use logical volumes?

thanks,
allan

The sys-fs/lvm2 package just contains utilities, it doesn't require
you to actually use LVM2. I also use it the same way as you. I now
have the lvm2 package and not device-mapper and everything still works
with my encrypted partition.

Thank you.  It worked fine.

Hello,

Background:
I upgraded a kde3 system to kde4. Along the way, to get past
blocking, I had to install device-mapper. Not sure if all system had
it before, as I never looked that closely. This particular system
is all reiserf, except for the swap partition. (please no file systems 
(flame) discussion). To see the old issues in greater detail [1].


Baselayout is 1.12.13 is installed.
All is good. Yesterday, I had to remove device-mapper to so that 
udev-146-r1 could install. So  reading a little bit on this, it seems
that I must have lvm2 installed?  lvm2 is installed  so
all is cool?



 Also, I have e2fsprogs installed, but, I do not think I need it, but
is it a good idea to just leave it installed? I do periodically connect
other hard drives to recover files and data, using a usb-2-ide(or sata)
cable on this system, so ext2/3/4 support is probably a good idea, but
is it absolutely required?


This is a critical system for me, so I just want to make sure
I'm not missing anything on the 'sunset' of device-mapper.
I have not reboot yet, since all of these changes.....

I did the same steps last Saturday & have had no problems.
I do need Ext2 for my  /boot  partition, which is normally not mounted;
otherwise, I use Reiserfs + Lvm2 .

BTW you can continue to use a few KDE 3 apps alongside KDE 4 :
you need to have separate dirs  ~/.kde3.5  &  ~/.kde4 .

It's included in lvm2 nowadays, hence the blocker.

Bye...

Thanks guys for the responses.
I'll reboot tonight and pray (cause I always do).


Gentoo has brought me closer to my maker.
(funny how that has worked out)..........
