[Wine] Problem write-access permissions

Hallo Winefriends!

I have a problem with write-access permissions of files under wine.
see you:

admin at max:~/.wine.test1/fake_windows$ wine foo.exe
...
trace:file:CreateFileW L"C:\\Windows\\win.ini" GENERIC_READ
FILE_SHARE_READ  cre
ation 3 attributes 0x80
trace:file:RtlDosPathNameToNtPathName_U
(L"C:\\Windows\\win.ini",0x4068f598,(nil),(nil))
trace:file:RtlGetFullPathName_U (L"C:\\Windows\\win.ini" 520 0x4068f300
(nil))

trace:file:CreateFileW returning 0xffffffff
trace:file:CreateFileW L"C:\\Windows\\win.ini" GENERIC_READ
FILE_SHARE_READ  creation 3 attributes 0x80
trace:file:RtlDosPathNameToNtPathName_U
(L"C:\\Windows\\win.ini",0x4068f598,(nil),(nil))
...

My questions:

- GENERIC_READ == readonly  correct??
- access=80000000 == readonly correct??

- Why is CreateFileW called, although readonly?

- Why again called CreateFileW, although previous call attempt fail?

- Why directory readonly?
  user "admin" is Owner all directories:


$ ls -la /home/admin/.wine.test1/dosdevices/c:/Windows
total 2946
drwxr-xr-x  20 admin admin    1024 Dec 31 09:53 .

- Can anywhere add a humanreadable warning to NtCreateFile()? Ex:
   "Warning: cannot create file %s, insufficient rights
(%o,%s)\n",unix_file,right_octal,unix_dir_owner

- existing a FAQ - Why to diag FileAccess?
