Unable to create a folder called "lib"

[tanjix]

Hi Guys,

I have a weird problem on my Vesta on Debian 8.8 installation - all my software inclduing Vesta is up2date.

When I try to create a folder called "lib" though FTP (proftpd), it fails with the error:

550: Permission denied

When I try to create a folder called "lib2" it works - it only fails when creating a folder called "lib".

What can I do? Is this a bug or any kind of security option, which I did not find so far?

Thanks! ;-)
