Re: Setting up a pbulk build environment

[Jason Bacon <outpaddling%yahoo.com@localhost>]

Sounds like you set up pbulk outside the chroot.� There's nothing to 
stop you from doing this (I don't use a chroot on OS X, because
it's not so trivial to create a pristine OS X env like I do for CentOS 
and NetBSD - I just use an old Mac with no extra software installed).

On https://wiki.netbsd.org/tutorials/pkgsrc/pbulk/, the useradd and 
pbulk.sh run are done in the chroot.

I played with these instructions for a while and decided to work at a 
lower level so I'd have more direct control and a better understanding.

If you want to understand the process more clearly, I would suggest 
going to https://netbsd.org/~bacon/Pbulk/index.html and studying the 
pbulk-* scripts there.

pbulk-new-chroot is run on the host and uses a tarball of a (hopefully 
pristine) CentOS or NetBSD installation.� I create the tarballs in a 
virtualbox guest, but the instructions there will work on a bare metal 
installation or any other VM.

pbulk-start-chroot enters the chroot env with minimal pollution from the 
host (null-mounts only the bare necessities).

pbulk-setup is then run inside the chroot.

Should a /home be created in the chroot filesystem?  Should a �-m� be added to the user add command here?  Or is the user add done outside of the chroot environment, or does it not really matter, i.e. ignore the error and create the user in either filesystem space?

If this is done in the chroot filesystem the file isn�t found since pkgsrc is mounted on /tree/pkgsrc, not /usr/pkgsrc.  And deeper into this script is another hard reference to /usr/pkgsrc which also can�t be found.  So is this deploy step executed in the chroot filesystem?

And if that�s the case, shouldn�t the Wiki guide reflect that the first step is just to verify that one can enter the sandbox and how it�s done, but that the remaining steps should be executed outside the sandbox?
