Task: "You have to configure the
/home's filesystem-mounting-method in such a way, so that all I/O operations will be always done in a synchronic mode, without the possibility of using the SUID authorisation. The mount options' changes must be done so that they would still remain in place after rebooting. Then you have to remount the filesystem so that the changes will be "activated" without the need for the system reboot.
(Hinted commands and directories to be used: mount -o remount, fuser, sync, /proc/mounts, /etc/fstab)"
After long thinking I've only managed to come up with:
[root ~]# mount -o remount,sync,nosuid /dev/mapper/fedora_12345-home
(Where the "
/dev/mapper/fedora_12345-home" is the file system found with the "
df /home" command.)
But there was no message after this command, so I can't determine if I done it right. Did I do (the part of the task) right?
What other commands/modifications to files do I have to do? (And which commands should I use to confirm I've done things right?)
