    Default Updating System Libraries

    Hello,

    I have a RedHat 6.2 installation that I would like to upgrade with the
    RedHat 8.0 system libraries (glibc etc.). I tried the following steps:

    o Saved the existing RedHat 6.2 /bin, /sbin. /lib to the following
    directories respectively:
    /RH62/bin,
    /RH62/sbin.
    /usr/i486-linux-libc5

    o Changed the symbolic links in /lib to point to /usr/i486-linux-libc5.
    o Copied over the RedHat 8.0 /bin, /sbin and /lib on to my RedHat 6.2
    machine.
    o Tested the commands from /RH62/bin. They work.
    o Created new links in /lib to point to the new RedHat 8.0 libraries.
    o Executed ldconfig.
    o Now when I try any of the commands from /bin I get the error "ILLEGAL
    INSTRUCTION".
    o I cannot recover back my system anymore.

    Questions:
    1. What am I doing wrong ?
    2. Is it possible to update system libraries this way ?
    3. The RedHat 6.2 machine is remotely located and can only be updated via
    a server machine due to security considerations.


    I could create a custom kernel on my RedHat 8.0 machine and install it on
    the RedHat 6.2 machine. This works without any problem.

    Since I have the RedHat 8.0 kernel on my RedHat 6.2 machine now, I would
    also like to upgrade the libraries to RedHat 8.0

    Thanks & regards,

    Running new libs for old kernel. Won't work. Must at least recompile
    kernel with new libs.

    No.

    You can do an install of RH8 to that machine, if you treat it like an
    FTP install.
