Summary: nfs4 mounts from script don't always work

Very odd: I have some NFS mounts which take place in
/etc/sysconfig/network/ifservices-eth0 so that when eth0 comes up, the script
determines which network it is in and (if appropriate) NFS mounts some
directories.
This worked great in openSUSE 10.X and 11.0, 11.1
but does not work in 11.2
It gets weirder. I set the script up so that it logs every statement via
logger, and the mount commands are succeeding. And nfs "stuff" of some sort is
happening, but for some reason I don't end up with any mounts.
For example:
...
From /var/log/messages:
Nov 28 15:17:06 worklaptop ifup-services: + mount -t nfs4 -o

If I issue the mount commands from the commandline, they work fine.
I even put an strace in the script and the mount *syscall* works:
31014 14:44:42.661157 mount("192.168.2.1:/multimedia", "/multimedia", "nfs4",
0, "soft,noacl,timeo=200,clientaddr="...) = 0 <0.186784>
and it even writes it into /etc/mtab:
31014 14:44:42.851267 open("/etc/mtab", O_RDWR|O_CREAT|O_APPEND, 0666) = 5
<0.000029>

31014 14:44:42.851605 mmap(NULL, 4096, PROT_READ|PROT_WRITE,

31014 14:44:42.851696 fstat(5, {st_mode=S_IFREG|0644, st_size=1144, ...}) = 0
<0.000019>
31014 14:44:42.851822 lseek(5, 0, SEEK_SET) = 0 <0.000019>
31014 14:44:42.851900 read(5, "/dev/mapper/system-root / jfs rw"..., 1144) =
1144 <0.000031>
31014 14:44:42.852061 write(5, "192.168.2.1:/multimedia /multime"..., 110) =
110 <0.000232>
31014 14:44:42.852374 close(5)          = 0 <0.000030>
31014 14:44:42.852467 munmap(0x7f9de6d44000, 4096) = 0 <0.000039>
31014 14:44:42.852567 close(4)          = 0 <0.000031>
31014 14:44:42.852657 unlink("/etc/mtab~") = 0 <0.000103>
31014 14:44:42.852844 exit_group(0)     = ?
Eventually, I discovered that the /etc/NetworkManager/dispatcher.d/nfs script
was interfering with this script. Disabling nfs (chkconfig --del nfs) lets
OTHER scripts that use NFS not run into weird problems.
I haven't a clue how to fix this.
