 That sounds like a good approach.

 Does anyone have any preference for syntax? Some suggestions:

 environment.shellAliases = ''
   alias ll='ls -lh'
   alias year='date +%Y'
 '';

 or

 environment.shellAliases = {
   ll = "ls -lh";
   year = "date +%Y";
 };

 or

 environment.shellAliases = [
   { alias = "ll"; command = "ls -lh" }
   { alias = "year"; command = "date +%Y" }
 ];


 I prefer the second example, but it might be a bit abusive on the 
 attribute set. We don't have tuples in Nix?
