Add /bin/dash in minimal.d

[victor gattegno]

On Ubuntu, /bin/sh is a link to /bin/dash.

So, as was added /bin/bash in minimal.d to be able at boot to use /bin/bash in mindi (for shell-scripts).

And as there is a link between /bin/sh to /bin/bash on Ubuntu (still in Ubuntu 12.04).

I would also add /bin/dash in minimal.d file in order to avoid Ubuntu mindi shell-script problems.

Even with the addition of /bin/bash and /bin/dash in minimal.d, on my Ubuntu 12.04 mindi still creates boot image successfully with the following values, in /usr/sbin/mindi:

EXTRA_SPACE=92160

BOOT_SIZE=40960

I wrote minimal.d file, but it's minimal.conf file.

Also add in mindi, after the same section about bash:

    # To improve support for distribution scripts, we now prefer to use dash as the std shell. Also fixes #600
    grep -q bin/dash $MINDI_TMP/minimal.lis
    if [ $? -eq 0 ]; then
        ln -sf bin/dash bin/sh
        LogIt "INFO: Using dash as default shell"
    fi

But these additions to minimal.conf and to /usr/sbin/mindi should be for Ubuntu only (and maybe for Debian if on Debian /bin/sh is linked to /bin/dash too), as there is no /bin/dash in RHEL nor in SLES.

/bin/dash is back in RHEL 6, but is not used in the /sbin shell-scripts, and /bin/sh is still linked to /bin/bash (as in SLES 11).

It seems that Debian has also /bin/sh linked to /bin/dash (that has to be verified).

I don't think this is required on Ubuntu: Now we systematically use /bin/bash instead of /bin/sh at restore time, whatever was available on the original distribution. And mindi has a dependency on bash now in order to force its usage. Next package will force bash installation in order to avoid any restoration problem.
