Following the instructions from arch-announce I did: $ sudo pacman -S filesystem --force Everything works fine except when umounting a NFS volume: $ mount /mnt/anubis $ umount /mnt/anubis umount: /mnt/anubis mount disagrees with the fstab The relevant line from fstab: anubis:/home/ricardo /mnt/anubis nfs user,noauto 0 0 And from mtab: anubis:/home/ricardo/ /mnt/anubis nfs rw,nosuid,nodev,noexec,relatime, vers=3,rsize=32768,wsize=32768,namlen=255,hard,proto=tcp,timeo=600, retrans=2,sec=sys,mountaddr=192.168.1.1,mountvers=3,mountport=33441, mountproto=udp,local_lock=none,addr=192.168.1.1 0 0 Anyone having troubles with NFS and the new mtab?
