    Default Can SUSE Linux mount ufs/ufs2 rw exec?


    *Does anyone know any method to make open Suse to mount usfs2 (unix file
    system2) with read write exec access? * Near a decade ago, there was
    Caldera-SCO open Linux 2.2.x kernel which I could recompile on its libc5
    platform to gain shared access to common place unix, BSD and Solaris and
    visa versa with native mode read-write exec mount. Beside text editor
    Crisp many games like Doom and Abuse or sound file like mp3 could be
    stored and run from shared ufs2 file system partition to save storage
    space (ext2, ext3 and ufs are close sisters all derived from ffs of
    ATT-BSD Unix, now Linux got more complex inodes to support more features
    i.e, block size variables). Are such becoming the things of past?
    Beside Server and Desktop use, I know some of you are using Linux as
    Universal system management OS to manage Windows. But I do not hear
    about managing Unix. This morning, I ordered a newest Debian DVD set
    and hoping to see some source files to support unix file systems. After
    my 5 years of ignorance to new technologies such as ext3, udev, ATA133,
    SATA and SAS, I am trying very hard to catch up after having bought a
    Dell Dimension Dual Core SATA II system recently.

    Whilst I am quite satisfied by open Suse 11. I even consider Suse 11
    over Fedora 9. *I want to point out that its install routine should not
    panic when it sees over 15 partitions on one or more drive.* I care
    less about being able to mount partition above 15th but it should not
    complain and abort installation. Now days, Debian Linux, Sun Solaris,
    open BSD care less about any existing partitions and install
    successfully. *So why not make it possible on the next Suse?* I had to
    set up a cheap dummy disk and later moved partitions using GPareEd from
    sourceforge.net then edited /etc/fstab. What a detour had I have to
    take? System originally had two Velociraptors 10000RPM WD3000BLFS drives
    that are rather pricey and I could not afford to buy one more for using
    as a dummy drive to just fool Install scripts.

    Linux and Unix always benefit from splitting file systems over multiple
    drives, particularly swap and /tmp on other drive as minimal. Even on
    Windoze, I rewrite registry to achieve same thing as unix. Combined
    multiboot environment naturally increases the numbers of partitions per
    disk.
    NTFS partition over 64GB, FAT32 partition over 32GB both slow down file
    access time dramatically plus I do not trust any OS that shares /tmp,
    /cache with OS core and libraries in the same partition anyway.

    I thank you for your time.

    If you read the history of UFS aka BFFS or FFS, you will see that there
    is no such thing as a standard UFS. Vendors each took it in slightly
    different directions. In fact it was the proprietary nature of Unix that
    allowed it to fragment.

    'Unix File System - Wikipedia, the free encyclopedia'
    (http://en.wikipedia.org/wiki/Unix_File_System)

    Linux was written from scratch and while the design of ext2 was
    influenced by UFS, the kernel has no code derived from Unix. (That was
    in fact what SCO was trying to falsely claim.) So the success mounting
    UFS would depend on the particular flavour, and is never quite full.

    Perhaps you should run one of the *BSDs, maybe it will give you better
    results.

    Even if you did get it to mount, you would still have issues with
    executable formats, system calls, libraries, etc. There used to be a
    compatibility layer, what was it called, iBCS or something like that, I
    think that's what you had in mind. I have no idea how well it works or
    what the state of maintenance is these days.

    Linux owes its design to Unix, but Linux is not Unix. The features
    inherited from Unix are elements like the HFS, the permission system,
    the device as file concept, the SUID bit, the API, the use of C as the
    system language, and of course the many applications.

    This was possible, until openSUSE-10.3, I believe. At that time
    Novell/SuSE-GmbH decided to adopt libata for hard drives, and with that
    came a 15 partition limitation.

    I guess no one in the user community complained enough against this
    limitation.

    You could try writing a bug report on this, if you don't like it, to
    see if you can influence the community away from the community accepted
    15 partition limitation.
