Re: [IBMiOSS] Question about Chroot

[Aaron Bartell <aaronbartell@xxxxxxxxx>]

Hi Jim,

Good question.  Yes, it is important to create all chroot environments in
/QOpenSys because it is a case sensitive file system.  This is because of
files like libC.a(n1) and libc.a(n2)  As you can see they are both the same
name but have a different case (upper-case C vs. lower-case c).  In a
case-insensitive file system the last file copied would overwrite the
existing file.

I see that's where Zend/MySQL resides.  I also see that /usr/local doesn't
appear to be sym linked into /QOpenSys/usr like other directories are (i.e.
/usr/lib).  Not sure why that is.

Opinion: Put your software in /QOpenSys/agileta
