This means it is not allowed to fail the\ncall, and also it does not know what the previous i_size was.

It will allow us to remove a bunch of pretty\nuseless init scripts and modprobes from init scripts.\n\nThe static device node aliases will be carried in the module itself. The\nprogram depmod will extract this information to a file in the module directory:\n $ cat /lib/modules/2.6.34-00650-g537b60d-dirty/modules.devname\n # Device nodes to trigger on-demand module loading.\n microcode cpu/microcode c10:184\n fuse fuse c10:229\n ppp_generic ppp c108:0\n tun net/tun c10:200\n dm_mod mapper/control c10:235\n\nUdev will pick up the depmod created file on startup and create all the\nstatic device nodes which the kernel modules specify, so that these modules\nget automatically loaded when the device node is accessed:\n $ /sbin/udevd --debug\n ...\n static_dev_create_from_modules: mknod \u0027/dev/cpu/microcode\u0027 c10:184\n static_dev_create_from_modules: mknod \u0027/dev/fuse\u0027 c10:229\n static_dev_create_from_modules: mknod \u0027/dev/ppp\u0027 c108:0\n static_dev_create_from_modules: mknod \u0027/dev/net/tun\u0027 c10:200\n static_dev_create_from_modules: mknod \u0027/dev/mapper/control\u0027 c10:235\n udev_rules_apply_static_dev_perms: chmod \u0027/dev/net/tun\u0027 0666\n udev_rules_apply_static_dev_perms: chmod \u0027/dev/fuse\u0027 0666\n\nA few device nodes are switched to statically allocated numbers, to allow\nthe static nodes to work. This might also useful for systems which still run\na plain static /dev, which is completely unsafe to use with any dynamic minor\nnumbers.\n\nNote:\nThe devname aliases must be limited to the *common* and *single*instance*\ndevice nodes, like the misc devices, and never be used for conceptually limited\nsystems like the loop devices, which should rather get fixed properly and get a\ncontrol node for losetup to talk to, instead of creating a random number of\ndevice nodes in advance, regardless if they are ever used.\n\nThis facility is to hide the mess distros are creating with too modualized\nkernels, and just to hide that these modules are not compiled-in, and not to\npaper-over broken concepts.
