What am I doing wrong? That's how it is supposed to work. nfs is a Unix filesystem, it obeys Unix user and permissions (unlike say VFAT or smbfs where it has to fudge these things). NFS will mount the filesystem using whatever is set on the server. You cannot override the permissions the server has set from the client You probably want to tweak your squash settings.

Or is it a bug?" I think it's a bug; systemd should stop NetworkManager.service only after all remote filesystems have been umounted. Could you boot up your machine after it hanged, and send the contents from "journalctl --boot=-1". That will give us the logs from the previous boot; perhaps we can see the problem. > I have to umount the NFS before poweroff everytime. Please tell me what can I > do to > resove this problem? I think it's a bug, but in the meantime (as a workaround) you can put the following script in /usr/lib/systemd/system-shutdown/nfs-force-umount: - #!/bin/sh /bin/umount -l /media/NAS - Make sure the script is executable.

There may be something amiss in your home directory. I think the easiest way to confirm/deny is to create a 'disposable' user account (mine is named 'tester') and see what happens when 'tester' starts xfce from a virgin home directory. I've solved many such problems that way. You can copy configuration stuff from your normal user's home directory to the test account one item at a time and see where xfce starts to segfault. Then back up one step :)

I think what Samuli was trying to say was that the suid bit is dangerous
if you give global execute permissions to the file, because then anyone
can run it as root. The default of rwx--x--- if safe because only root or
a member of the messagebus group can execute it.
My problem was that the messagebus user was not a member of the
messagebus group thanks to a mismatch of IDs in /etc/{passwd,group} - I
don't know whether this is also the cause of the error messages on
Helmut's system.

Hi, Is it possible to mount an NFS share from XFCE4? I suspect the answer might have something to do with gvfs or fuse, neither of which I know anything about.

If this is impossible, then I'd be ok with an approach that will allow a regular user to mount any network share with the mount command. Thank you, Chris
[gentoo-user] System hangs when poweroff with NFS mounted
Hi all, I swithed to Gnome3 last week, and the systemd is needed by gnome3.8, so I used systemd to replace the openrc now. Howerver, my system always hangs when I try to poweroff. I have NFSv3 filesystem mounted via WiFi, it's managed by the Networkmanager. so it seemed that the wireless connection was cut off before the NFS was unmounted? I searched this problem and modified my fstab line like this: NAS:/data/media/NAS nfs _netdev,x-systemd.automount,x-systemd.device-timeout=10ms,rw,soft,vers=3 0 0 It's worked under the wired connnection, but the wireless connection still hangs, Is there any thing should be changed? Or is it a bug? I have to umount the NFS before poweroff everytime. Please tell me what can I do to resove this problem? Thx

Thanks for your feedback!
I will check back here ... in the next week I will have another old box
to update, this time from a kernel 2.6.27-gentoo-r8 ... with gcc 4.1.2,
and udev 124-r2 !!
It was kept in this state to keep good old vmware-player-1.x running.
Now I deployed a new gentoo-based KVM-server there ... at last!
