Re: [PATCH] MODSIGN: Fix including certificate twice when the signing_key.x509 already exists

Looks the '$(shell pwd)' in Makefile was call '/bin/pwd' but not 'the shell builtin pwd'. But, in case the behavior is different between shells, I think used '$(shell /bin/pwd)' will be better for make sure we call /bin/pwd from coreutils. I will send a second version of this patch, please consider for accept if we need this change. Thanks a lot!

[PATCH] MODSIGN: Fix including certificate twice when the signing_key.x509 already exists
This issue was found in devel-pekey branch on linux-modsign.git tree. The x509_certificate_list includes certificate twice when the signing_key.x509 already exists. We can reproduce this issue by making kernel twice, the build log of second time looks like this: ... CHK kernel/config_data.h CERTS kernel/x509_certificate_list - Including cert /ramdisk/working/joey/linux-modsign/signing_key.x509 - Including cert signing_key.x509 ... Actually the build path was the same with the srctree path when building kernel. It causes the size of bzImage increased by packaging certificates twice.
