- Where did Linus get 99% of his MODELS for Linux? Ans: USL and BSD
- UNIX. "We stand on the shoulders of giants..."
-
- In other words, he used models for OS concepts that originated
- in UNIX(tm). The system calls, the library calls, the utility
- names, the program names, the memory models, the networking, the
- file systems, the concepts of UID,GID,SUID,SGID, sticky bits,
- mountable filesystems on a tree, etc. These are all basic
- features of UNIX(tm) that he used when creating Linux. You'd
- be VERY hard pressed to find OS concepts these days that HAVEN'T
- passed through a UNIX(tm) kernel at some time in the past. For no other
- reason than UNIX(tm) is the OS most researchers work with on
- a day to day basis and what they tend to hack on. Even micro kernels
- like MACH and probably NT borrow QUITE a bit from the UNIX(tm) system
- in system call names and symantics as well as utility and program
- names. Hell, even that pathetic MSDOG lifts I/O redirection and
- directory command names from UNIX(tm), amongst other things.
