Recipe: cannot copy files into the root with the nest-part command.

[Doug Barbieri]

I cannot copy files from a nest-part folder into the root.

For example:

 # bzr-builder format 0.3 deb-version {debupstream}+{revno}
 lp:~snapcpp/snapcpp/snapCMakeModules
 nest-part modules lp:snapcpp snapCMakeModules .

fails.

Here is the output from the command:

 $ bzr dailydeb --allow-fallback-to-native snapCMakeModules.recipe snapCMakeModules
 Building tree.
 Retrieving 'lp:~snapcpp/snapcpp/snapCMakeModules' to put at 'snapCMakeModules/snapCMakeModules-{debupstream}+{revno}'.
 bzr: ERROR: Failed to rename /home/doug/src/ppa/snapcpp/snapCMakeModules/snapCMakeModules-{debupstream}+{revno}/.bzr/checkout/limbo/new-1 to /home/doug/src/ppa/snapcpp/snapCMakeModules/snapCMakeModules-{debupstream}+{revno}/.: [Errno 16] Device or resource busy

And I can see the reason--the nest-part algorithm creates a temporary folder, then tries to rename that folder to the target folder (which is the root, which already exists).

This wouldn't be a problem if the launchpad.net system would allow the "run" command, but it is blocked. (see https://launchpad.net/bugs/608450‎).

I could have just done this instead, and been done:

# bzr-builder format 0.3 deb-version {debupstream}+{revno}
lp:~snapcpp/snapcpp/snapCMakeModules
nest-part modules lp:snapcpp snapCMakeModules snapCMakeModules
run cp -aux snapCMakeModules/* .

:)

Is there any workaround to this out there? Or is this something that will be fixed in the future (fingers crossed)?
