Subject: Re: [IBMiOSS] Question about Chroot

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.

n1 - http://bit.ly/2blNx3O
n2 - http://bit.ly/2blNapS

I'd like to explore using /usr/local for where I would put the chroot'd

environment and my software. Again, does it matter?

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

My understanding of your best practice advice is to create a
directory similar to : /home/jim/mychroot and copy everything there.

The slide (p13 see: http://bit.ly/litmis-ifs-containers) shows:
/QOpenSys/Myspace/home/QOpenSys.. where I believe you put the chroot
in the example.

Does it matter? I'd like to explore using /usr/local for where I

My guess is it does not matter but then again..
