[Trisquel-users] Re : Partition table suggested for installing three GNU/Linux systems

[lcerf]

And it seems like 16 GB should last quite a while. I only wonder if I were to  
install games in /opt if 3.2 GB would get strained.

Just do not separate /opt from / (that you can enlarge if you wish) and you  
will get flexibility! You already plan to use the same type of filesystem.

There might be a performance hit if a partition is bigger than it needs

Not that I am aware of.
