The FHS document applies to Linux, not to Unix. The symbolic link of /bin to /usr/bin only exits in current Unix file system hierarchies. I just checked an AIX 5.3 system and a Solaris 10 system, both have this symbolic link.
Yes, I know some unix systems does it that way, but as I mentioned, it's not permitted under the FHS
I don't know of a Unix distribution that abides by FHS. As I mentioned before, Unix tends to use hard links rather than symbolic links. A perfect example is vi, ex, edit, and vedit are all hard links to the same inode.
That's because they have ALWAYS been the same executable. Even the earliest BSD systems (on which ex/vi first appeared), they have always been two personalities of the same executable. That's who Bill Joy wrote it.
I think unix systems get away with it because they have virtually nothing in /usr/bin, they stick just about everything in /opt, don't they. So they can still have a small root partition, even while including /usr
That was the intent, but it doesn't seem to old in practice. With AIX, a lot of stuff gets put in the lpp directory with symbolic links from other directories to the lpp directory. I have also seen symbolic links in /usr/bin that point to /opt/bin. It was one of those ideas whose implementation fell short of expectations.
Nothing in AIX should be regarded as typical on its own. It's a horrid perversion of BSD. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
