Description isakmt 2009-04-09 15:01:34 UTC 
Description of problem:

rpc.statd is running as root after installing nfs-utils rpm.

Before installing nfs-utils package, "/var/lib/nfs/statd/sm" directory is
not exist. rpc.statd does mkdir the directory when first starting of
/etc/init.d/nfslock. Because the dir's owner is root, rpc.statd does
not drop root privilege and outputs warning message to syslog.

"statd running as root. chown  to choose different user"


Steps to Reproduce:
1.If you already install nfs-utils, erace it.
   # rpm -e nfs-utils
2.Install nfs-utils rpm.
3. # /etc/init.d/nfslock start
4. # ps -fp `cat /var/run/rpc.statd.pid`
5.See UID of rpc.statd
  
Actual results:
UID is root.

Expected results:
UID is rpcuser.

patch for nfs-utils.spec

mkdir sm dir and chown it in postinstall script 
prevents rpc.statd from mkdir the directory 
with root privilege.
