Thanks for the link! But, perhaps, I am walking up the wrong path.
What I am really looking for, and this could be because of my inexperience with Crux, is a path to the distribution's tree with which to synchronize my system, and from which I could download and install packages.
I am trying to edit my pkgmk.conf file in accordence with the installation handbook:
What is the correct path to a mirror and the crux source tree?
It is mentioned that the link is an example, so I am also wondering about the brackets instead of quotes in the syntax.
Would the link require quotes, as all the other parameters in the file?
