A very similar "ENOTSUP" problem is being reported with coreutils-8.32

I don't understand that bug report. The strace diff you mentioned in
Comment 4 looks like the new mknod command is working. And yet the
original bug report says new mknod command is complaining "Operation not
supported".
Is the problem that some filesystems don't work with the chmod
/proc/self/fd/NNN trick, and that it worked for you (the strace diff)
but not for Mohan (the original bug report)?
