cygwin installation on a synology NAS drive

[Andrey Repin]

Greetings, Dr. Volker Zell!

>>> I created a shared folder on a Synology NAS and mapped it to a Windows 7
>>> host system. Both Windows 7 and Synology NAS have the same named user
>>> account (part of admin groups). The named user has full access to the
>>> shared folder on the NAS side.
>>
>>> I then tried installing latest cygwin versions (x86/x64) on the mapped
>>> drive (at the root filesystem) but got permissions errors from setup.exe
>>
>>> Setup was actually able to create the cygwin directory structure but
>>> could not write to the log file.
>>
>>> Creating directories/files and writing to files is no problem with
>>> windows tools on the mapped drive.
>>
>>> Anybody else tried this setup or knows what's going on here ? Or is a
>>> cygwin installation on a NAS not supported ?
>>
>> Have you authorized admin session on NAS before starting setup?

> How do you do this ?

I'm mapping disks twice :)
First as regular user, second as elevated.

>> Setup by default request elevation and that change all authorization context

>> Can you try to start elevated cmd.exe, make sure you have correct maps/write

> Same result

Opss... bad.
