Subject: Group Permissions on root folders problem (Windows 10 TP build 10061)

I did a fresh cygwin-64 (setup-x86_64 version 2.870) install under
build 10061 of Windows 10 Technical Preview.

The group permissions in the root look wrong.

$ ls -lA /
total 321
drwx---r-x+ 1 Brian Brian               0 Apr 29 10:31 bin
dr-xr-xr-x  1 Brian Brian               0 Apr 29 10:31 cygdrive

drwx---r-x+ 1 Brian Brian               0 Apr 29 10:30 var

I'm logged on with a Microsoft account and ran the installer as an
Administrator.

This is a particular problem running ssh-host-config -y
$ ssh-host-config -y

$ id
uid=197608(Brian) gid=197608(Brian) groups=197608(Brian),405504(High
Mandatory Level),114(Local account and member of Administrators
group),197611(HomeUsers),544(Administrators),545(Users),4(INTERACTIVE),66049(CONSOLE
LOGON),11(Authenticated Users),15(This
Organization),68521(MicrosoftAccount+brian AT buchananworldcorp DOT com),113(Local
account),66048(LOCAL),262180(Cloud Account Authentication)

Am I doing something wrong?

Is there a way to fix the permissions or a workaround for installation?

Thanks,

Brian
