Well you actually _need_ a working (and obviously running)
vserver-kernel first.
To determine, if the running kernel "supports vserver" or if the vserver
options
are enabled, you could use [1] *after* you successfully installed the utils.
Another option is, to grep your config (or probably config.gz if it's
enabled in
your .config) for the relevant options:
CONFIG_VSERVER_LEGACY
CONFIG_VSERVER_NGNET
CONFIG_VSERVER_PROC_SECURE
CONFIG_VSERVER_HARDCPU
CONFIG_INOXID_NONE
CONFIG_INOXID_UID16
CONFIG_INOXID_GID16
CONFIG_INOXID_UGID24
CONFIG_INOXID_INTERN
CONFIG_INOXID_RUNTIME
CONFIG_XID_TAG_NFSD
CONFIG_VSERVER_DEBUG
Please note, that those CONFIG's may differ if you are using a
patch-version
<vs2.0 (these are from vs2.0-rc5).
