After a recent HDD crash I did a clean install of Linux Mint 15 on a new disk. Seeing the potential problems with having backups of my documents and eclipse workspace, I realized that a smarter backup solution would be to take the entire home folder. Thus I partitioned my new HDD with
/opt as separate partitions. My intention with this scheme was to use
/ for the system,
/home for documents etc that will be backed up, and
/opt for stuff that are sort of self-contained and do not require a backup, such as Virtual Windows installations that sometimes need.
I noticed today when I was setting up the VM that it uses a folder in
/home to store the vdi files, by default. When I changed the location of that folder to
/opt I came to realize and remember that
/opt has 755 permissions.
Does it make sense to put a folder e.g.
/opt/vmand try to put the vdi files there? I assume that Virtualbox will run with my normal user permissions and thus won't be able to write there anyways.
Does giving such a folder 777 permissions solve the problem? My feeling is that the writing bit would be OK, but I am worried that this might cause more trouble later on.
If the above scheme is really error-prone, what options do I have? It would be a pity to leave
/optas is (120 GB) only to create another partition. I could,in theory, resize
/opt/and create another partition
