I released another TEST version of the next upcoming Cygwin release.
The version number is 1.7.34-003.
For almost an year I have used, on Win7 U 64 and Cygwin 64, an USB key (to
backup my Cygwin HOME), formatted NTFS, both with Cygwin 1.7.33 (i.e. using
/etc/{group,passwd}) and test Cygwin (like 1.7.34 using only a default
nsswitch.conf). On this USB key the files and folders had alway owner ‘angelo’
and group ’None’.
Now I reinstalled from scratch Win7 U 64 (the same, only I used an usb
bootable instead of CD/DVD), and so reinstalled Cygwin64.
To reinstall Cygwin 64 I did this:
1. Installed the default (next, next,.. in setup-x86_64.exe), i.e. Cygwin 1.7.33
2. I didn’t start Cygwin but with Explorer I renamed /etc/group in
/etc/group-save and the same for passed.
3. Copied nsswithch.conf from my backups (it contains the default)
4. Restarted setup-x86_64.exe and installed the test release, i.e. Cygwin
1.7.34.
Now on that USB key the files and folders have owner ‘Unknown+User’ and group
‘Unknown+Group’. I have also some difficulties in having full control.
Sometimes I have to start MinTTY as administrator.
Are all these facts to be expected with 1.7.34 in a new reinstallation of the
OS?
If re-installation created new SID's for you machine, than the old SID
stored in the USB STICK file descriptors are not recognized.
Compare the output of /usr/bin/mkpasswd.exe
with a previous copy of /etc/passwd, if available
Or look with windows explorer at "properties->security" for
some of the files in the STICK
For example, when I use that USB key on OS X (which can only read NTFS
partitions), the files have owener ‘angelo’ and group ’staff’ as on my OS X
HOME.
To summarize, the same USB key has:
OS
OWENER GROUP
Cygwin 1.7.33/34 before OS reinstallation angelo
None
Cygwin 1.7.34 after OS reinstallation Unknown+User
Unknown+Group
probably chown / chgrp will be helpful
OSX 10.10

Ciao,
