more than one distro, same /home
I like to have more than one distro installed on my computer, right now I have two version of ubuntu (precise pangoline and 11.10). All my distro share the same /home (that is on a separate partition) but, of course, I have different accounts to be used on different distro (/home will host an account "xxxx" for use with 11.10 and "yyyy" for use with 12.04).
I have been trying to share the same data on both distros (same documents, file for password storage, dropbox account etc.) following the suggestion of a magazine I organized links using nautilus (for example the folder "documents" in "xxxx" is linked to a "document" folder in "yyyy" using the possibility in nautilus to obtain a link that you can move between folders. Looks like this kind of link, however, is a symbolic link and I wonder if an hard link wouldn't be more appropriate for this use. As a matter of fact if I delete the original folder (I may want to install a diferent distro tomorrow) I will no longer have access to those file with a symbolic link.
I understand that hard links point at the same inode and deleting the first link will not affect the ability of the second to show the file or folder. I wonder: If I decide to erase a folder to free space on the system do I need to search for all hard links to get rid of the data?
