[grsec] Grsecurity + Vserver patch (gradm2 installation problem)

[Fredrik]

Hi,

Hope it's Okay to post to this list even if it is probably a modified
grsecurity patch to play nice with vserver (or it may be the other way
around)

I have tried several vserver+grsecurity patches (both for 2.4.x and
2.6.x kernels) and they compile fine and I get lots of nice grsec log
messages when booting. When I try to install gradm2 (gradm-2.1.7) I get
the following error:

# make install
Installing gradm...
Installing gradm_pam...
Installing grlearn...
Installing gradm manpage...
Could not open /dev/grsec.
open: No such device or address

make: *** [install] Error 1

I get this for all of the different patches I have tried [1] anyone know
what it could be?

$ gradm --status
Could not open /dev/grsec.
open: No such device or address

$ stat /dev/grsec
  File: `/dev/grsec'

Or if anyone know if grsecurity (with rbac) works with vserver and which
patch I should use?
