I was installing Linux Mint 17 for a virtual machine on my PC, and I decided it was a good idea to record the whole process. Furthermore, I also installed Adobe Reader manually on Linux Mint 17, and so by watching this video you will also know how to do this. If you’re trying to do what I’ve done within this video, make sure you do not deny shell access and lock the password for the regular user or users that you want to use, because if doing so you will not be able to log into the system. Of course, if you follow my video closely, deny shell access means editing the /etc/passwd file, and lock password means editing the /etc/shadow file by executing the command line passwd -l [username].
Moreover, if you’re trying to edit the /etc/fstab file as I’d done in the video, make sure you make a copy of the original /etc/fstab file first before editing the original /etc/fstab file. /etc/fstab file is very important, because it tells the system how to load up the devices such as hard drive, and screwing this file up will prevent your system from loading/booting. Having the original copy of /etc/fstab file will allow you to restore it in the case that you screw up the original /etc/fstab file.
If you are going to pay close attention to my part of editing /etc/fstab file, you will notice that I’d made error on adding rw option to the /tmp and /dev/shm devices, but you will also notice that I had correct the errors in the video few seconds later. Basically, rw option is correct, but in the video, before I made the option as rw I had the option as wr. By having the option as wr, the system won’t recognize this option. So instead of wr, it should be rw.
rw is a permission option. By adding rw option to /tmp and /dev/shm, the /tmp and /dev/shm devices won’t allow anything to execute commands in these devices, but these devices only allow whatever to read and write to them. Anyhow, you can check out this video right after the break. Enjoy!!!
