Hi,

I am developing a diskless embedded system (aka the target) that uses Linux=
 as its Operating system. The target connects directly to my PC (XP).=20
I would like to boot the target to an NFS server, where is will get the fil=
e system.
I would like to use the Cygwin NFS server in the following manner:
- Create the target file system on the host (the build host is Linux)
- Save it to the NFS server. This can be done as part of the build process =
(send the build results to the NFS server instead of storing locally).
- Boot the target via NFS

I am currently encountering the following problem:
When the file system is created, some special files (actually devices), e.g=
. /dev/console and /dev/tts/0, are craeted using "sudo mknod". When this is=
 done to a regular Linux directory, these devices are create with uid and g=
id as "root". But when created on the Cygwin NFS server, they are created w=
ith my uid and gid.
Later when the target tries to boot from the NFS, it will not use these dev=
ices, since they are not owned by "root", and the boot fails.

How can I get these devices to be owned by "root" (i.e. uid:gid =3D=3D 0:0)=
?=20

Thanks

Eli Stern
