Hi! This is an ebuild for device-mapper, the new version of the Logical Volume Manager present in 2.5 or greater kernels. It should almost certainly go in the same place as the LVM libraries (sys-libs). Reproducible: Always Steps to Reproduce: (Flagged the bug as "normal" instead of "enhancement" because, well, anyone with 2.5+ and LVM is up the proverbial creek without it :-) About to submit an ebuild for lvm2-user (the userspace utilities for LVM2, the complement of lvm-user.
Created attachment 10975 [details] ebuild for sys-libs/device-mapper Fun for the whole family, including the dog.
Also see the bug just following this one for the userspace utilities: http://bugs.gentoo.org/show_bug.cgi?id=19745
Note: if bug 22768 gets added to the kernel the lvm2 and device-mapper ebuilds will need to allow people to build it on a 2.4 kernel, but could check for a version with the LVM2 backport patches applied.
