Note the call to setuid. This should not be necessary but it was. So something is checking the real uid instead of the effective uid for unmounts. Problem in the kernel build? Anyway, this works. Use this at your own risk. With it installed suid root anybody can unmount anything... I used my own string class, you'll have to change that anyway, // 04/17/11, L. E. Day #include #include #include int main(int argc, char * argv[]) { LedString cmd("umount "); int stat; stat = setuid(0); if (stat) { fprintf(stderr, "setuid failed with status %d. This program must be installed suid root.\n", stat); exit(stat); } if (argc != 2) { fputs("usage: rum string\nPasses string exactly as specified to umount\n", stderr); exit(1); } cmd += argv[1]; stat = system(cmd.c_str()); exit(stat); } -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

As "umount -i" works and works correctly I think the best solution for 11.4 is to recommend that approach. i.e. when a non-root user wants to unmount an NFS file system they should use umount -t /mount/point I will make sure that when nfs-utils-1.2.4 is added to Factory that it is build with --enable-libmount-mount. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

The new package uses libmount support. So this will soon be fixed in Factory. For 11.4 we recommend the work-around of using "umount -i".
