Emacs marks the file as read-only (%%) and asks every time a question
after pressing C-x C-s:
File<name here> is write-protected; try to save anyway? (y or n)
PROBLEM
The constant prompting "Y/N" makes writing to a network drive location
exessively hard. It's nuissance to have to be able to confirm every
save action.
There doens't seem to be way to turn of this prompting.
SUGGESTION
The logic of checking if file is write protedted or not does not seem
to be reliable under Cygwin regarding network drives. The Permissions
probably don't come through correctly for Emacs to examine them.
A) Offer option to turn of confirmation
B) or bypass write protection checks under Cygwin
TEST DATA
Here is an example under Cygwin Emacs:
(file-attributes "/cygdrive/z/tmp/test-epackage.el")
=> (nil 1 4294967295.0 4294967295.0 (20194 11100) (20194 19792) (20194
19792) 437 "-rwxr--r--" t (-1735557 1952988 . 8890) (30147 . 13405))
Under Cygwin Bash shell it looks like this:
$ ls -la /cygdrive/z/tmp/test-epackage.el
-rwxr--r-- 1 ???????? ???????? 437 Dec 9 20:02
/cygdrive/z/tmp/test-epackage.el
Note: the uid and gid information is not available from this non-domain
network drive.
