Not necessarily.
If you can restrict Cygwin to a known set of directories, you can use
Cygwin-only permissions in those directories and let Windows do whatever it
wants with everything else.
Here’s my fixperms script, which keeps both sides happy:
#!/bin/bash
if [ -z "$1" ]
then
for d in /usr/local ~/bin ~/tmp
do
echo Fixing permissions in $d...
chown -R $(id -nu) "$d"
find "$d" -exec "$0" {} \;
done
elif ! setfacl -kb "$1"
then
echo " ...in $1"
fi
Modify the list of Cygwin-only directories at the top of the script to suit
your local situation.
I don’t bother doing this to the entirety of c:\cygwin*. I only include
directories I’m likely to open in both Cygwin and Explorer in that list.
You might have to run it a few times to fix everything, due to the way Windows
permission inheritance works. (I prefer that to the alternative, which is the
breadth-first find(1) hacks: http://stackoverflow.com/q/1086907)
You’ll probably also need to run it as Administrator, at least the first time.
After that, new permission changes should be ones your user has the ability to
revert without Admin level privileges.
If you’ve set your Cygwin HOME directory to be the same as your Windows user
profile directory, be sure NOT to include ~ in the list of directories you
modify with this script. There are files under %APPDATA% at the very least
that will break horribly if you run this on them. Do this only on files that
your user personally owns and uses, not files owned and used by Windows on your
user’s behalf.
Directories you run this script on do not show the “incorrectly ordered”
symptom in Explorer.
