I am using ubuntu 12.04 in VirtualBox, and I created two accounts with usernames lyg and ygl.
I found a directory VBOXADDITIONS_4.1.18_78361/ in /media, questions got into my mind when I type "ls -l /media/" in my terminal. Below are two outputs:
- When I boot and login as lyg,
-xr-xr-x 4 lyg lyg 2048 Jun 5 22:33 VBOXADDITIONS_4.1.18_78361
- Reboot and login as ygl,
-xr-xr-x 4 ygl ygl 2048 Jun 5 22:33 VBOXADDITIONS_4.1.18_78361
So, why do the user and group change?
