Requirements:
- Version 2.6.25 of the Linux kernel with sysfs, procfs, signalfd, inotify,
- unix domain sockets, networking and hotplug enabled.
+ unix domain sockets, networking and hotplug enabled:
+ CONFIG_HOTPLUG=y
+ CONFIG_UEVENT_HELPER_PATH=""
+ CONFIG_NET=y
+ CONFIG_UNIX=y
+ CONFIG_SYSFS=y
+ CONFIG_SYSFS_DEPRECATED*=n
+ CONFIG_PROC_FS=y
+ CONFIG_TMPFS=y
+ CONFIG_TMPFS_POSIX_ACL=y
+ CONFIG_INOTIFY=y
+ CONFIG_SIGNALFD=y
- For reliable operation, the kernel must not use the CONFIG_SYSFS_DEPRECATED*

these group names with only the rootfs mounted, and while no network is
