There was a problem hiding this comment. These files do not need to be removed. There was a problem hiding this comment. But shouldn't they be? If I was testing out some new software on my machine, I wouldn't want it to leave behind unnecessary files or directories. Perhaps we could move these commands into a sub-section describing how to completely purge Nix from your system? There was a problem hiding this comment. It may be better to have a section which lists all files that are (typically) existing/generated by Nix and what their purpose is. Based on that a reader can easily decide what they need to remove. |

||
| <para>Then you need to remove the line that references Nix from your | ||
| <filename><envar>$HOME</envar>/.profile</filename>. Assuming that your username | ||
| is <literal>user</literal> it should look something like this:</para> | ||
|
|
||
| <screen> | ||
| if [ -e /home/user/.nix-profile/etc/profile.d/nix.sh ]; then . /home/user/.nix-profile/etc/profile.d/nix.sh; fi # added by Nix installer | ||
| </screen> | ||
|
|
||
| <para>There might also be some configuration files in | ||
| <filename>/etc/nix</filename> that you need to delete:</para> | ||
|
|
||
| <screen> | ||
| sudo rm -rf /etc/nix | ||
|

| <para>Finally, on a multi-user installation of Nix, you will also need to remove | ||
| the <literal>nixbld[0-9]</literal> users.</para> | ||

| sudo userdel nixbld0 | ||

This and removing the sourcing of nix-profile.sh are really the only steps that are required.
