I'm trying to change the just the group id of a file with sb-posix:chown
like this (sb-posix:chown "file.txt" -1 501), but I get an error message
saying "The value -1 is not of type (UNSIGNED-BYTE 32)."
After reading about posix chown I expected to be able to use -1 to
signify that the owner of the file would be unchanged.
Any tips on how to get this to work?
