OK -- I tried it, converted all my files to ntsec and played around
with some programs. And, I'll go right back, remove all NT-level
permissions and turn off ntsec.
Files saved by Windows applications such as JBuilder (actually Java
but a Windows JRE) end up as follows:
-r-xr-xr-x 1 root none 59486 Nov 20 20:46 MainFrame.java*
Without ntsec, the file looks as it should:
-rw-r--r-- 1 chris users 59486 Nov 20 20:46 MainFrame.java
Furthermore, backing up the Cygwin directory to a CD with a general
purpose CD writer program such as Nero doesn't work anymore because
Nero can't read some of the files.
Windows is not Unix and Windows programs typically don't care about
file permissions (especially things like "should a file be
executable"), thus files created by Windows programs will always end
up with incorrect permissions in Cygwin with ntsec turned on.
Back to the original question: Would it be possible to either
(optionally) turn off the owner check in ruserok() or to respect the
UID/GID values in the extended attributes if "CYGWIN=ntea nontsec"
plus something like "ntea_uid"?
Cheers,
