Subject: [PATCH] Trust guix store directory
|
|
|
|
To be able to execute binaries defined in OpenSSH configuration, we
|
|
need to tell OpenSSH that we can trust Guix store objects. safe_path
|
|
procedure takes a canonical path and for each component, walking
|
|
upwards, checks ownership and permissions constrains which are: must
|
|
be owned by root, not writable by group or others.
