I am basically trying a clean install on my laptop to dual boot mint and arch. I want to have some shared storage space for them but separate roots and also get to keep my dot config files from my homes. If I used the classic shared /home strategy there would be username conflicts and other things too consider.
So this is what I came up with:
/swap (2 gigs) arch root(10 gigs) arch home(5 gigs) mint root(10 gigs) mint home(5 gigs) /mnt/storage(everything else)
This design allows me to keep my configs in case of a clean install and also provide that storage partition to which folders such as "Downloads" and "Videos" link to via symbolic links. My question is: what drawbacks can it have, and if I were to use the standard separate /home setup where would I locate my storage directory?
