Hi Corinna,
Ref: https://cygwin.com/ml/cygwin/2015-02/msg00798.html
- [ANNOUNCEMENT] TEST RELEASE: Cygwin 1.7.35-0.4
Something for your list of things to think about ... and do later ;-)
For a directory, the 'creator owner' should have sufficient permissions. That is, at least 'full control
minus delete'; full control is good. (yes, as far as I can tell)
(with respect to setfacl, I made a similar remark)
That has changed in 1.7.35-0.4 with respect to chmod ...
As result one cannot 'touch' (create) a file in a subdirectory, that has been created using Explorer.
Henri
