36 I know this topic is quiet old.
37 On my systems I only have /dev/{null,console} , and let udev managed the
38 rest.
39 When I do the install, I remove all the files in /dev (except those
40 two), and run mount --bind /dev /mnt/gentoo/dev , then I do the install,
41 and it works fine.
42
43 Is there any reason for not doing this, and then recommend that the
44 users that don't use udev/devfs to run MAKEDEV ?
