** Mount /home/deck/nix to /nix
|
||
|
|
The default /nix is too small and it could be modified by OS releases. We want to use something in our home folder since that will be untouched in upgrades.

|
# TODO: /home/nix gets owned by root but it should be owned by deck:deck for single-user nix installs
|
||
|
|
|
||
|
|
# TODO: nixos-installer adds this to /home/deck/.bash_profile , will this be wiped out in updates?
|
||
|
|
# if [ -e /home/deck/.nix-profile/etc/profile.d/nix.sh ]; then . /home/deck/.nix-profile/etc/profile.d/nix.sh; fi # added by Nix installer
