    Any success on Version 2 RC2 ? — I can’t get /lib/modules to unlink since is a read only file system, if I copy /lib to /Database/rootfs/lib after removing /lib I can link the new /lib to /Database/rootfs/lib anymore since /lib is missing.

    Thanks,

    Brief history: I was disappointed I couldn’t properly shutdown my ZeroShell VM during (occasional) main server maintenance. So I decided to dig into this adventure… Successfully! Maybe it’s not the cleanest way to do it, but it simply works…

    Works on: VMware Server 2.0.0, ZeroShell-1.0.beta12-VMWARE.zip, others not tried.
    Tools required: a brain.
    Time required: about 15min. (if you know what you’re doing).
    Hope: there’s nothing wrong here.

    ZeroShell for VMware essentially is a Live distro. It keeps Databases and configurations into a persistent device, but the system itself is set up on a ReadOnly filesystem. Unfortunately, vmware-tools installation needs to create some symbolic link and to copy files into this ReadOnly file system. That means we need to transform it in a ReadWrite one (and persistent! I remember you / is in RAM!). Let’s see what we can do…

    Step 1: ReadWrite filesystem setup and vmware-tools installation files copy:
    1. Shutdown your VM and install a supplementary CD device mounting vmware-tools disk image. The file is called “linux.iso” and can be found in the VMware installation directory.
    2. Start ZeroShell and gain root access in the console (not SSH because vmware-tools installation will reset your network device)
    3. Type “loadkeys it” to load Italian keyboard (if you’re Italian of course), because we need to type a lot!
    4. Mount the secondary cd with the vmware-tools on a temporary directory


    a. mkdir /mnt/hdd
    b. mount -t auto /dev/hdd /mnt/hdd

    5. Copy tar.gz installation file to the /Database directory and uncompress it

    cp /mnt/hdd/VMxxxxxx.tar.gz /Database
    cd /Database
    tar -xvzf VMxxxxxx.tar.gz

    The second CD/DVD has done all his job. We can safely delete this hardware on next reboot.
    Now you should have a directory called “vmware-tools-distrib” which contains installation files. What we need now is a ReadWrite copy of the /sbin and /usr:

    cd /Database
    mkdir rootfs
    cd rootfs
    mkdir sbin && mkdir usr
    cp -a /sbin/* /Database/rootfs/sbin
    cp -a /usr/* /Database/rootfs/usr

    We also need a copy of the current modules directory that is inside /lib:

    mkdir modules
    cp -a /lib/modules/* /Database/rootfs/modules

    Now we are ready to switch to a RW filesystem:

    mount -o remount,rw /
    unlink /sbin && ln -s /Database/rootfs/sbin /sbin
    unlink /lib/modules && ln -s /Database/rootfs/modules /lib/modules
    unlink /usr && /cdrom/usr/bin/ln -s /Database/rootfs/usr /usr

    Now RW filesystem is ready.

    Step 2: Prepararing for vmware-tools installation:

    mkdir /Database/vmware-tools
    cd /Database/vmware-tools
    mkdir etc
    cd etc
    mkdir init.d
    mkdir rc.d
    cd rc.d
    mkdir rc0.d
    mkdir rc1.d
    ...
    mkdir rc6.d

    Step 3: vmware-tools installation:

    cd /Database/vmware-tools-distrib
    ./vmware-install.pl

    At this point, vmware installation should ask where we want to install and which folder contains rc0.d, rc1.d etc. folders. Of course you will answer:

    /Database/vmware-tools/TheFolderItAsksFor/

    So if it asks you “/usr/bin” you’ll answer “/Database/vmware-tools/usr/bin/” and so on… (note the trailing / at the end of the path). It will complaint about non-existing folders. Just accept to create them. Everything that goes to /Database/vmware-tools/xxx is OK.

    The installation will terminate properly. Now you only need to “configure” vmware tools:

    cd /Database/vmware-tools/usr/bin
    ./vmware-config-tools.pl

    It should complaint that some modules have not been properly configured for your system and asks you to compile. Just tell “NO” to all questions and… Voilà! “vmware-guestd” process should be now running and perfectly working.

    Step 4: Post installation.
    Vmware-tools sadly creates a “vmware-tools” folder inside /etc… Which is in in RAM!!!! That means if we do not backup this folder, on the next reboot we’ll lose our configuration.

    cd /Database/vmware-tools
    mkdir startup
    mkdir startup/etc
    mkdir startup/etc/vmware-tools
    cp -a /etc/vmware-tools/* /Database/vmware-tools/startup/etc/vmware-tools

    Now we only need to restore that folder (and links to vmware files) on every startup. Save the following script “run.sh” in “/Database/vmware-tools/startup”:

    #!/bin/bash
    mount -o remount,rw /

    unlink /usr && /cdrom/usr/bin/ln -s /Database/rootfs/usr /usr
    unlink /sbin && ln -s /Database/rootfs/sbin /sbin

    cp -a /Database/vmware-tools/scripts/etc/* /etc

    /Database/vmware-tools/etc/init.d/vmware-tools start

    Now WebLogin into ZeroShell. Go to the panel “Startup/Cron”, select “post boot”, enable status, and add the following line:
    /Database/vmware-tools/startup/run.sh
    Save and reboot and enjoy your vmware-tools!
