[Buildroot] /dev nodes files

[Buildroot] /dev nodes files

[Daniel Mack]

This has been discussed before, but I don't know if there was any
result, so I'm asking again.

After each build, the ixnodes in project_build_arm/uclibc/root/dev are
regular files rather than inodes, which prevents users from exporting
that directory directly as NFS root. Most people run custom scripts to
fix that, but I wonder whether there is any change to get that fixed in
BR2 directly.

The problem is that mknod can't create the nodes when not run as root,
and fakeroot doesn't help much in this case. Would it be an option to

 a) move the invocation of makedevs from target/*/*mk to some higher
    level. Actually, all fs deployment targets do the same thing, and
    that could be simplified.
 b) Let users choose whether to use 'fakeroot' or 'sudo' to create the
    inodes. The latter would need some augmented system priviledges, but
    as an option, that shouldn't harm.

Any oppinion about such an approach?

Ehh, that's on purpose (E.G. so you don't need root permissions to
build). Just select the tarball target and extract it on your nfs
server.

What would this buy us that the tarball target doesn't give?
