Hi,
Something's wrong here, on boot i too receive some messages while
mounting/activating LVMs, but they mount OK.
Checking saw i have both /lib/libdevmapper.so.1.01 and
/lib/libdevmapper.so.1.02. Both belong to "device-mapper":
# qfile /lib/libdevmapper.so.1.01
sys-fs/device-mapper (/lib/libdevmapper.so.1.01)
# qfile /lib/libdevmapper.so.1.02
sys-fs/device-mapper (/lib/libdevmapper.so.1.02)
The sizes are *different* the times are equal:
# ls -l /lib/libdevmapper.so.1.01
- -r-xr-xr-x 1 root root 25056 2006-03-05 10:50 /lib/libdevmapper.so.1.01
# ls -l /lib/libdevmapper.so.1.02
- -r-xr-xr-x 1 root root 58036 2006-03-05 10:50 /lib/libdevmapper.so.1.02
But running "revder-rebuild" gives me nothing to rebuild:
# revdep-rebuild --ignore --library /lib/libdevmapper.so.1.01 -p vv

All prepared. Starting rebuild...
emerge --oneshot -p vv =sys-fs/device-mapper-1.02.03

These are the packages that would be merged, in order:
...END...
The problem here seems to be that LVM2 (which is build statically, and
no static USE-flag present). sys-fs/lvm2-2.02.03
Checked - is a static binary, but must somehow be build against the
older library (code), so the said messages/warnings.
Will try rebuilding 'device-mapper' then 'lvm2' and rename the minor
version library.
Or some other app is links against the old version (reverse deps):
# dep -L device-mapper
sys-fs/device-mapper:
        app-crypt/truecrypt-4.1              >=sys-fs/device-mapper-1.00.08
        sys-fs/cryptsetup-luks-1.0.1-r2
>=sys-fs/device-mapper-1.00.07-r1
        sys-fs/lvm2-2.02.03                  >=sys-fs/device-mapper-1.02.03
...END...
