With latest linux kernels (can't recall on the spot when I saw this for the first time, something around 2.6.23.XX I suppose) I get this warning on dmesg:

warning: process `nginx' used the deprecated sysctl system call with 1.33.

(Linux 2.6.24.2)

I guess that at this moment this message is not harmful, but in future maybe it can lead to problems.

maybe a small change in source code can fix this, but I'm not a developer so I'm only able to report and not to fix, I fear :)

nginx uses sysctl to learn KERN_RTSIGMAX only, because procfs is not available in chroot. Failed sysctl is not harmful in modern and future kernels, because it's unlikely you will want to use fragile rtsig method instead of epoll.

Probably, I will add --without-rtsig_module to disable rtsig autodetection.
