However, I do, and it has nothing to do with coreutils and everything to
do with your file systems. I suspect that /home is mounted to a
traditional Linux file system where any file name (other than a NUL or /
byte) is valid, while /media is mounted to a removable drive which is
probably formatted as a FAT file system, and the FAT specification
forbids certain characters such as ':' in file names. Since the kernel
can't create your choice of file name on that system, it must fail instead.
