0.2.1

Bugfixes:

• 'pack' no longer stop if a file is missing
• Do not attempt to pack files from /proc or /dev
• Stops vagrant without --use-chroot from overwriting files
• Downloads busybox instead of using the host's /bin/sh
• Correctly packs the dynamic linkers from the original machine
• The tracer no longer considers execve() to always happen before other accesses
• Fixes pytracer forking the Python process if the executable cannot be found
• Improves signal handling (but bugs might still exist with SIGSTOP)
• Fixes a bug if a process resumed before its creator (race condition)

Features:

• -v flag also controls C tracer's verbosity
• Detects (but doesn't handle yet) i386 compatibility and x32 mode on x86_64
• Stores working directories and exit codes of all processes in database
• Added reprozip reset [-d dir] to reset the configuration file from the database
