Ken was lucky as he did not need to honor constraints from other operating
Hard disks are also much simpler to use than optical media with complex meta
BTW: do you know why UNIX did create something that is completely
non-extensible like cpio or hard to extend like tar? We had to wait until 1997
for Sun to propose a nice extensible archive format that has become the base
for the POSIX.1-2001 TAR extension headers.
Do you know why UNIX had a "ps" command that could be used to create random
junk output in 1982 because there was no interface to get reliable process
information? At the same time, UNOS written at Charles River Data Systems by
former AT&T engineers could do this right already.
