The programming interface to quotas to highly variant across different versions of UN*X. I understand it even differs across versions and releases of some Linux flavours. A useful starting point for attempting such an implementation might be the "quotas.c" file from the "samba" product. This runs on a wide variety of UN*X platforms, and even the briefest glimpse at their code shows the portability problems that need to be addressed. So yes, by all means add quota support. But we need to think a little more about exactly how and where. A related issue: should this support be in "pam_mkhomedir.c" itself? Or perhaps rather in a separate PAM module? One advantage of separating it is this portability aspect: "pam_mkhomedir.c" is clean and portable, whereas anything programming quotas will, of necessity, have to be considerably less clean to achieve portability. Hope that helps your considerations. -- : David Lee I.T.
