We can always pass to strace(1) the exact list of system calls we want. So there's no essential need for new strace selectors. The only thing that stopped me from implementing --trace=3Dopen,execve,... argument for /usr/share/buildreqs/strace_files is that actually I would have to deal with stat/stat64 difference somehow. --I7xMaAXwyt9AGI17 Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (GNU/Linux) iD8DBQFF/ZiWfBKgtDjnu0YRAmpkAJ4uKu/fczIDINWFgm5tw6wv+J3TJQCgrNym NrkKE7T/sOikpJo+5nDMqjY= =CZBg -----END PGP SIGNATURE----- --I7xMaAXwyt9AGI17--
