I noticed that commit 55922c9d "Linux 3.0-rc1" caused dhcp-client 2.0pl5-19.1sarge3 (in Debian Sarge) to report SIOCSIFNETMASK and SIOCSIFBRDADDR errors (though, it seems to me that these errors are not affecting the functionality).

Starting portmap daemon: portmap.
I guess this program is doing something like below.
if grep -q ^2.6 /proc/sys/kernel/osrelease then do ioctl for 2.6 kernels else do ioctl for 2.4 kernels fi
We need to widely announce that userland applications using branches based on /proc/sys/kernel/osrelease need to be fixed.
Regards.
