[Nix-dev] problems installing on a shared system

[Erick Tryzelaar]

Hello again,

It's been a while since I last played around with nix, so I wanted to 
check it out. I'm having some problems though. First off, the machine 
I'm on has /home/erickt symlinked to another directory. After I built 
nix and tried to install it, nix-update errored out saying that nix 
doesn't support being installed in a path with a symlink. I've manually 
specified the full path, but it would be a lot more handy if I didn't 
have to. The server may change the symlink in the future, and I'd hate 
to have to rebuild nix all over again if that happened.

Second, after I installed it with the full path, I'm getting this 
strange error. It looks like nix can't find tar, and I can't figure out 
how to install it Any idea what's going on?
