Re: [IBMiOSS] /QOpenSys/QOpenSys? -- OPENSOURCE

All,

In my experience this comes up very often with 3rd party software that has been compiled for AIX. The software has hard-coded paths of "/usr", "/usr/lib", "/usr/bin" and the like -- and frequently its hard-coded into the program.

The workaround, of course, is to use chroot. But now if you try to use it in conjunction with software that expects /QOpenSys (such as a script with a bang-path starting with /QOpenSys) the /QOpenSys causes it to fail. Thus the symlink, which solves the problem.

In a perfect world, none of this stuff would be hard-coded... but alas, the world is not perfect.

Since the symlink takes up almost no DASD, its worth having it there.

Frankly I don't think that anything as part of PASE itself requires it to
be there, however if you have any software that does chroot("/QOpenSys")
it's handy since then you can still reference /QOpenSys paths from within
the chroot. I have no idea what software does this, but I'm fairly certain
that nothing within PASE (SS1 option 33) needs it. YMMV.

Don't delete it! I don't recall why it is there; but it serves a

purpose.

Maybe Kevin Adler can comment.

Over the weekend I applied the latest CUM for V7R3. I was hoping

would be there, but it wasn't.

Anyhow, I found something else interesting while looking around. I

not

sure how this happened:

bash-4.2$ cd /QOpenSys
bash-4.2$ ls
IBM QOpenSys bin etc lib64 sbin var
QIBM QSR download lib opt usr
bash-4.2$

Both QOpenSys directories have the exact same creation date.

3/16/2016.

The subdirectory has a change date of 3/16/2016 as well.

Unfortunatley

it

has a last access date of today since I was like "Wha? Why is this

there"

and went in to see what is there.

It seems to be a copy of the /QOpenSys directory.
