Thanks for hints, this does explain a bit from what I see, however
something is still missing.

When I tried what you wrote

# git -C /mnt/src/main merge

or what I made from reading man pages and Git Book referenced in Git
Primer,

# git -C /mnt/src/.git --work-tree /mnt/src/main merge

all I get is

fatal: No remote for the current branch.

so evidently no merge is actually done. Something in my setup is wrong
or missing. It's late here now, tomorrow will be another day to try
something :)
