pkgsrc as non-root user?

[David Chanters <david.chanters%googlemail.com@localhost>]

Hi all,

I'm reading the FAQ for pkgsrc which talks about using pkgsrc as a
non-root user:

http://www.netbsd.org/docs/pkgsrc/faq.html#non-root-pkgsrc

But despite reading it a few times I am still unclear what it is I am
supposed to do.  The first paragraph there says:

"If you want to use pkgsrc as non-root user, you can set some
variables to make pkgsrc work under these conditions. At the very
least, you need to set UNPRIVILEGED to “yes”; this will turn on
unprivileged mode and set multiple related variables to allow
installation of packages as non-root."

Which is fine -- I can edit mk.conf as apropriate.  But is the
expectation that pkgsrc still resides under "/usr" -- and if so, am I
supposed to manually fix up the permissions on /usr/pkgsrc/* myself so
that a non-root user can rw there?

Furthermore, if that's not the case and the assumption is that for a
non-root user to use pkgsrc they're to have /usr/pkgsrc in some other
location, how does the editing of mk.conf as mentioned in the FAQ
relate to this?

I hope this makes sense!

Thanks in advance,
David
