In the process (so far successful) to replace udev by mdev on a hardened server, I noticed that gradm directly depends on udev. I don't know for sure if it's possible: I don't know what CDEPEND is and I don't find it there http://devmanual.gentoo.org/general-concepts/dependencies/index.html. But I tested a successful build of raw gradm source without a problem (udev not present on the system actually), and mdev seems to be well aware of /dev/grsec so maybe udev direct dependency could be fixed. Reproducible: Always
