Getting back to the original point of this thread:
When I installed Trisquel 7 to my external 1TB SSHD I first used Gparted to
make three partitions: 30GB (ext4) for the OS, 8GB (linux -swap) for swap,
and 864GB (xfs) for Data. Running the Trisquel live DVD, I chose "something
else" (i.e., the checkbox at the bottom of the list of choices) and then
chose the 30GB partition for mounting the root (/) folder and the 864GB
partition for mounting the home (/home) folder.
What I ended up with was as nicely functioning Trisquel installation in which
all my data is in the 864GB partition, and all my OS is in the 30GB
partition.
When I run the other Trisquel OS that is installed on the 320GB internal HD,
I see the data on that external SSHD residing on the 864GB partition and
another home (/home) folder listed among the folders on the 30GB partition of
the external SSHD. However, that latter home folder is empty, insofar as the
internal Trisquel OS is concerned. When I run the external Trisquel OS, this
distinction disappears and there is just one home folder. That's how it's
s'posed to work.
Back to the current rants: Wine will take care of many proprietary
applications, some better than others. If you try an independent way of
running proprietary S/W, don't expect Trisquel to support its idiosyncrasies.
My installation of Windows 7 (which came with my Lenovo T420 notebook) didn't
object when I used Gparted to squeeze it into the corner of my HD, and
Trisquel happily resides in the balance of that HD without any interferences,
but with the luxury of being able to extract data from the Windows portion of
the HD seamlessly and without having to reciprocate ... I don't even try to
get data from the Trisquel installation back into Windows when running the
Windows OS.
