Dybmh, It did not happen using VirtualBox. I was using Antix as host.
Well, I have a a partition with home folders of four distributions. I realize that I may face problems, but let me see. That is why the person who mentioned this way (internet info) said that we have to give it as /home/distribution. That will keep them apart. The total Home partition of four distributions is 1GB (Mint not included yet). One big difference between serious computer users and myself is that
I use computer only for forums and fun.
At the moment I am not taking up sharing on VirtualBox machines. My concern is about sharing of the Home data between the four distributions that I have in one partition. Do you think Samba would be able to do that? Will I need Samba installed in all distributions or just one will do?
