Hi! Maybe someone has tried UML kernel on grsec machine? I took that Debian precompiled UML kernel, run it with "linux root=/servers/moon " (that /servers/moon is one of my production servers' ext2 partition image), but UML says:
... mconsole (version 2) initialized on /root/.uml/N7Jm6p/mconsole unable to open root_fs for validation Initializing stdio console driver NET4: Linux TCP/IP 1.0 for NET4.0 And that's all... no further messages, nothing. The modules required for this kernel has been put inside the image. The host kernel is with grsec patches,. and it tells in /var/log something about resource overstep: Aug 16 17:13:51 localhost kernel: grsec: attempted resource overstep by requesting 494927872 for RLIMIT_STACK against limit 8388608 by /usr/bin/linux[linux:29530] uid/euid:0/0 gid/egid:0/0, parent /usr/bin/linux[linux:2566] uid/euid:0/0 gid/egid:0/0 Any ideas?
