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.....
