Regards, Aravinda -------- Original Message -------- Subject: RE: Fwd: Re: makedumpfile security key enhancement using SIAL Date: Wed, 28 Mar 2012 07:07:49 -0400 From: Luc Chouinard To: Aravinda Prasad Libsial is meant to be a pluggable entity and as such should not require other pieces to be there ( crash or gdb). I want to create project and associated git for the library soon. For now you can extract libsial from the crash tar ball and manage any modifications using a simple patch mechanism. When the git is available, we can merge any fixes or enhancements you created for support of makedumpfile. Makedumpfile and crash would then feed off of specific branches/versions of the git repository. If you have any suggestions or want to help in setting up a public git / project page for sial, please let me know. -Luc > -----Original Message----- > From: Aravinda Prasad [mailto:aravinda@linux.vnet.ibm.com] > Sent: Wednesday, March 28, 2012 1:31 AM > To: Luc Chouinard > Subject: Fwd: Fwd: Re: makedumpfile security key enhancement using SIAL > > Forwarding to your s2sys email ID.
