Magic Banana wondered:
" I do not understand whether you are talking about a live system (e.g.,
created with Etcher) from which you access a filesystem (hence the 'mount')
or about a regular install but on an external disk."
Brief answer: either TQ installation procedure _demands_ that the target
partition be mounted at root (/).
and strypey also asked:
" Like MagicBanana, I'm a bit confused about what you are trying to do. Are
you trying to use bootable USB stick to install Trisquel on an external USB
hard drive? If so, why? If not, where am I misunderstanding your goal?"
Originally my goal (when this all started) I was preparing to upgrade the
internal HDD of my T420 laptop, but while I was doing something for which I
wasn't fully qualified (a.k.a. inept) the Windows partition became
inacessible ... R.I.P. and I wanted to get another, larger HDD ... my choice
has built-in flash buffer, so it turned out that it was perfectly happy
acting as an alternative USB-connected operating system. Both the internal
and external drives have had Trisquel_7 operating systems for several years
with minimal hassles.
Now comes Trisquel_8 ... but rather than risk disaster using GParted to move
a lot of files on the external USB-connected hard drive in order to make room
for TQ_8, I grabbed the IOMEGA 1TB drive and proceeded to make it look a lot
like the first USB-connected HDD ought to be looking: Both TQ_7 and TQ_8
operating systems, one to use every day, the newer one to try out and also to
find new hassles when weather permits.
From all the forum discussions that I've read, the Live USB stick appears to
be the standard stepping stone for installing Trisquel to a more permanent
storage device. Etcher.io might have presented some obstacles, but the
raspberry.pi folks saved me a lot of hassles by providing three simple steps
for installing etcher.io on the T420:
"https://www.raspberrypi.org/magpi/pi-sd-etcher/"
From another thread, it appears that the etcher.io web page could use some
additional work, but Google short-circuited the quest for a simple procedure
for me.
Between the three HDD's, my T420 now has five Trisquel OS's, all under firm
control of grub. I could probably use the HDD that has the solid state buffer
in place of the T420's internal HDD, but that can wait ... lots of file
shuffling to do.
