There is subtle issue of assigning username in the literal form and I think using uid instead of username is fine. The file standard hierarchy does not specify the user directory name in detail and we just need to maintain symbolic link of /home correctly.

i would suggest to rely on $HOME - because it can be changed to redirect 
the homedir - eg temporarily or for specific emulation, testing or 
isolation purposes. this is based on experience. i used to use getpwnam 
but at some point in the past hit a problem (i forgot what it was now) 
but i had to switch to $HOME.
