[buildd-tools-devel] schroot variables

[shawn wilson]

I want to change the path where schroot looks for what to copy.
However, I'm getting a strange error:
 % schroot -c test -- ls /
E: 19basefs: error: copyfiles file '/etc/schroot/copy/test' does not exist
E: test-eb5cb9ea-cee1-49f5-a82d-9a334ad61b69: Chroot setup failed:
stage=setup-start
 % ls -l /etc/schroot/copy/test
-rw-r--r-- 1 root root 8 Oct 10 05:26 /etc/schroot/copy/test

# schroot.conf
[test]
type=directory
description=Test
users=swilson
directory=/opt/schroot/test
profile=default
setup.basefs=base/test
setup.copyfiles=copy/test

I see setup.d/20copyfile tests -n and -f - both should be true:
swlap1 /etc/schroot # cat copy/test
/bin/ls
swlap1 /etc/schroot # ls -l copy/test
-rw-r--r-- 1 root root 8 Oct 10 05:26 copy/test

I'm guessing I'm not doing something or setup.copyfiles is incorrect?
The goal is to have the profile be the same and just modify the
copyfiles and basefs. basefs, which I created 19basefs for but isn't
getting to that branch because I don't have a base/test yet. However,
as soon as I touch base/test, and try to start, I get:
E: 19basefs: error: copyfiles file '/etc/schroot/copy/test' does not exist
E: test-e8d69f6a-a158-41e9-bff7-8831eb258c34: Chroot setup failed:
stage=setup-start

(Minor modifications to handle directories which I see issues with,
but it isn't what I'm seeing, so....)
