[Freedos-kernel] Checking NUL directory/drive is broken in 2042

[Nando Eva]

Was using FreeDOS 1.1 2040 kernel? previously and could check for drive or directory existence with the NUL device:
If exist c:\nul echo C: existsIf exist c:\mydir\nul echo C:\mydir exists
This behavior is broken with 2042, no longer being able to identify if a drive/dir exists anymore.
Can the devs please add the previous behaviour with NUL drive/directory identification?
Thank you

I tried to reproduce this here, and I think that it behaves exactly as
it should.

can you be more specific how it fails ?

Tom, screenshots at http://imgur.com/a/h9x9c showing kernel 2042 always identifying e:\nul as present (attrib e:\nul or if exist e:\nul), even though it is not. Kernel 2041 correctly identifies it as not present.

A fix for this would be great so I can again check for drive/dir existence using the NUL filename.

Thank you,Nando
