Short explanation: it is not a bug it is a feature :) Longer explanation: Debian has moved to so called multiarch system that now only have ld-linux-x86_64.so.2 in /lib64 and all other libs in /lib/x86_64-linux-gnu/ as by default my script cannot see that link (ldconfig -p does not see it there) so i just try creating link and on debian it will point to correct location. On openSUSE it will "fail" which is expected as there is already library in place. So maybe I should add "echo this will fail on non debian" (comment is in script stating that already)

noted. I see the "will fail" comment in the script. thanks.

once IN the chroot, if I exec

ldconfig

it returns

ldconfig: /lib/ld-linux.so.2 is for unknown machine 3.

checking

ls -al /lib/ld-linux.so*
    -rwxr-xr-x+ 1 root root 152418 Apr  8 10:52 /lib/ld-linux.so.2

file /lib/ld-linux.so.2
    /lib/ld-linux.so.2: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), dynamically linked, BuildID[sha1]=0xfa97022309e1748552b2d492f78c1439bbfdc9f5, not stripped

it does NOT seem to interfere with ldconfig execution and its cache creation

rm -f /etc/ld.so.cache 
ldconfig
    ldconfig: /lib/ld-linux.so.2 is for unknown machine 3.
ls -al /etc/ld.so.cache
