Only if the LVM user tools are dynamically linked (old ones won't be),
and assuming that the "tools" part of the commands don't change, only
the "lib" part. I'm not sure that the latter will be true. Looking at
the user commands, for example the LVM_CHECK_IOP macro hard-codes the
LVM_LIB_IOP_VERSION into the "tool" part of the binary, rather than
doing the checking inside the library (which is really what should do
all the interfacing with the kernel).
Until this is fixed (it may be harder than it seems, and may make for lots
of restrictions on what can be changed in the user commands), the only
thing that the liblvm.so versioning allows is for multiple dynamically
linked user tools to be installed (iff they are in different directories).
Cheers, Andreas
