bpt-v0.1.5

Various style and consistency fixes

bpt-v0.1.4

Canonicalized bbuild file name format to include version. This fixes a cache invalidation bug which was based on file name.

bpt-v0.1.3

fix: Bedrock mount cleanup

Previously, simultaneously attempted to remove a directory and detect if
it is non-empty (and couldn't/shouldn't be removed) in one go.  However,
did not handle EBUSY.

On Bedrock, /etc is a mount point and attempting to remove it results in
EBUSY.  Handle this explicitly.
