| Untested.  Gabor, can you please try this?

Compiled fine.

utils/mountd/Makefile:

LIBBLKID = -lblkid

-lblkid doesn't enough in dependency, needs -luuid

Is this problem in my e2fsprogs install?

BTW, I'm not sure about usage of sm-notify

My nfs startup script looks like:

idmapd
exportfs -ar
mountd
statd #--no-notify
nfsd 8

$ ps fax
10860 ?        Ss     0:00 mountd
10862 ?        Ss     0:00 statd
10875 ?        S      0:00 [nfsd]
10876 ?        S      0:00 [nfsd]
10886 ?        S      0:00 [lockd]
10887 ?        S      0:00  \_ [rpciod]
10888 ?        S      0:00 [nfsd]
10889 ?        S      0:00 [nfsd]
10890 ?        S      0:00 [nfsd]
10891 ?        S      0:00 [nfsd]
10892 ?        S      0:00 [nfsd]
10893 ?        S      0:00 [nfsd]

Looks like no sm-notify started, even I mount something from a remote
host. If I start sm-notify by hand, it exist, strace output attached.
Same apply on glibc 2.3.
