Don't share the /bin directory between OS installs. Doing so is liable
to leave one of the two OSes unbootable at some point.
That's assuming /bin is on the / partition. if /bin is a symlink to
/usr/bin [as seems to be fashionable nowadays] and /usr is its own
partition, then sharing that partition can be made to work, with some
care. But I don't think that's what you have.

For future reference, there's `uname -m`.
But again: I would recommend just giving each OS its own partition.
That's a lot less likely to break.
Cheers,

That's just for my personal binaries, not the system /bins. I suppose
the expected thing would be to have that stuff in /usr/local/bin but I
like to keep all my personally made stuff in one partition separate from
stuff made by the OS or by installing things officially, that way I just
mount my partition on to the FS of any OS and I've got all my stuff
exactly perfect right away and I basically never touch anything else
except sometimes you hafta tinker with a few files in /etc. The only
hitch has ever been the jump to 64 bit, which gives me a different set
of my binaries and a different zsh. Maybe I haven't figured out the
best protocol for that.

That's best, because it won't change with any 64 bit kernel, I think.

Yup, I'm quite a partitioner, there's just the shared stuff to to with
zsh and my few personal binaries. Nice to unpack everything from one
suitcase and be right at home.

Gentlemen:
Now that I have both 32 bit and 64 bit versions of various binaries,
whereas I used to just store them in a /Bin directory which is on my
path, now, if I'm jumping back and forth between 32 bit Debian and 64
bit Debian, whereas previously different installs could share the same
/Bin directory (all being 32 bit previously) now I hafta be able to
distinguish 32 from 64, so I'm thinking to symlink /Bin to either /Bin32
or /Bin64 and I'm wondering if there might be a simple way for zsh to
make that link for me based on knowing if either itself, or the kernel
is 32 or 64 bit. I could test the output of 'uname -r' of course, but
I'd not be surprised if zsh can do it more elegantly and robustly than
checking for substrings in the kernel name.
