<para>Nix has two basic security models. First, it can be used in
|
|||
|
|
“single-user mode”, which is similar to what most other package
|
|||
|
|
management tools do: there is a single user (typically <systemitem
|
|||
|
|
class="username">root</systemitem>) who performs all package
|
|||
|
|
management operations. All other users can then use the installed
|
|||
|
|
packages, but they cannot perform package management operations
|
|||
|
|
themselves.</para>
|
|||
|
|
|
|||
|
|
<para>Alternatively, you can configure Nix in “multi-user mode”. In
|
|||
|
|
this model, all users can perform package management operations — for
|
|||
|
|
instance, every user can install software without requiring root
|
|||
|
|
privileges. Nix ensures that this is secure. For instance, it’s not
|
|||
|
|
possible for one user to overwrite a package used by another user with
|
|||
|
|
a Trojan horse.</para>
