Re: [PATCH] Force UNIX domain sockets to be built in
when i had that module modular and added to the initrd, udev didn`t work, though. same error message: udevd[1226]: init_udev_socket: error getting socket: Address family not supported by protocol not sure if i did a mistake here anyway, this message is not obvious to the end user. i like the kernel being modular, but i also like it if things "just work" - and with "allmodconfig", modular UNIX domain sockets seem to create hassle. (see http://forums.gentoo.org/viewtopic-t-476363-highlight-.html or http://forums.gentoo.org/viewtopic-t-463793-highlight-.html ) so, if this patch is being rejected, maybe it would be useful if udev would give a proper hint, if it`s missing this kernel feature. btw, udev documentation telling this: - The kernel must have sysfs, unix domain sockets and networking enabled. (unix domain sockets (CONFIG_UNIX) as a loadable kernel module may work, but it is completely silly - don't complain if anything goes wrong.) furthermore, if this needs to be modular, then i`d please have tcp/ip networking modular, too. :) regards roland ps: not being a skilled programmer, so this is mostly an admins/users perspective. > > From: Bodo Eggert <[EMAIL PROTECTED]> > Date: Mon, 31 Dec 2007 13:09:43 +0100 (CET) > > > As suggested by Adrian Bunk, UNIX domain sockets should always be built in > > on normal systems.
