Yes, that was a good hint, thanks. The "problem" is that I am Admin on one machine, but not on the other, and / was writable for the admin group for some reasons, and only on this machine.

But, why does e.g. t0004 behave more gracefully (and skips) and t5539 just dies ?

./t0004-unwritable.sh ok 1 - setup ok 2 # skip write-tree should notice unwritable repository (missing SANITY of POSIXPERM,SANITY)

(And after changing the group of / t5539 passes, and so does t0004)
