Hi  R. Berber-

Thanks for the cool info. Can't wait to check it out :-)

Hi R.


Yes. 'The recommendation is to not use anything.'

There are too many accounts specific to the OS like SYSTEM.

I think they serve a purpose. e.g. a process can run as system.

I vote for leaving well enough alone on this one.

I will just set permission at command line in mintty for stuff like ssh
authorized_keys etc. and not touch permission outside of mintty.

Have a cool night.

Thanks,
Robo-loki

I think the recommended way is using the mkpasswd command.  Actually the 
recommended procedure is not to use anything.


Just run that command and take a look at the output.  You have to filter 
out most lines, only add the user you want.


Now run it with --help, you'll see you can list 'local' users AND domain 
users.  I put quotes on local because you can also specify local to 
which computer (as long as it is running SMB, I think).


Its about the same for groups: mkgroup.

Hope this helps a little.

Hi all

Since there are no adduser or addgroup, I guess I'd create those files
manually off /etc.

Then I'd run passwd.

After that put in /etc/fstab

none /cygdrive cygdrive binary, posix=0, noacl, user 0 0

Close all processes.

That would give me a posix permission set up, right?

I read something about windows ignoring some dos bit with a file permission
but that is outside of cygwin...right?

Lastly, with acl you open an administrator cmd shell. With posix can I
escalate to root and stay away from admin cmd shell?

Is anyone else using posfix setup in general or mostly acl?

Thanks for any help!

Hi all-

I found in the manual about the execute bit permission being ignored in
filesystems with acl. That answered one question above. I can just take
advantage of how exe heuristics work.

If I find myself in a position where it needs administrator rights via a
shell, will it interfere with my posix permissions, users, or groups once
the /etc/groups and /etc/password and fstab are already setup?

Did the fstab entry above look okay for posix permission?

Thanks for any assistance !

HI all -

I had a privilege escalation window come up for instance when running a
system supplied configure script for sshd ( I think ). It gave the choices
yes or no prompting to choose carefully for noacl permission mode or acl
translation setup. I think that prompt is very good. Will it (administrator
mode) always at least ask or identify which type of setup if required?

Thanks as always,
Robo-loki
