To Whom It May Concern: I have a question about the licensing involved in using the Berkeley Labs Checkpoint Restart package (so hopefully you will bear with me if this question becomes convoluted). Libcr is covered by LGPL but from reading your paper "The Design and Implementation of Berkeley Lab's Linux Checkpoint/Restart", it seems that in order to checkpoint a program (even when you checkpoint it by linking against libcr - not using cr_run) the checkpoint needs to utilize vmadump. However, vmadump is protected by GPL so would that automatically cause libcr to be GPL instead of LGPL or is there something else that mitigates that? Also, does libcr utilize cr_module at all? If not, what is the purpose of cr_module and does it affect the licensing for libcr in any way? Essentially I'm trying to checkpoint a proprietary program and wondering what the limitations on licensing are so I can determine whether to utilize BLCR. Any insight or help you can give will be greatly appreciated. Thank you very much for your time. Thank you, Richard Hu rhu_at_opnet_dot_com
