Ubuntu 15.10 X64 /etc/resolv.conf issue #79

Closed SquirrelCoder closed 8 years ago

SquirrelCoder commented 8 years ago

Hi,

I have always installed this script on Debian 8 Jessie, and every time after the installation has finished I checked /etc/resolv.conf entries, and there was some warning below the screen "Permission Denied" , so I think this script makes /etc/resolv.conf file "immutable" so it doesn't get after each reboot written, BUT now I wanted to test Ubuntu 15.10 and this file isn't "immutable" , and I can edit it, so I think, that this may bring issues after the server reboots. I think it would be better, if we make this file immutable? sudo chattr +i /etc/resolv.conf UPDATE_1: So I wanted to configure the servers and these are the 2 errors:

chattr: Operation not supported while reading flags on /etc/resolv.conf
chattr: Operation not supported while reading flags on /etc/resolv.conf

so I assume you have added this command to the script but it doesn't work somehow!

stat /etc/resolv.conf

I have ran the command you mentioned, and the first line is: File: ‘/etc/resolv.conf’ -> ‘../run/resolvconf/resolv.conf’

The problem is we're writing the local DNS address to the target of the symbolic link, but try to run chattr on the symbolic link itself, which fails.

Reference note: this is probably the same issue as #71, possibly #72.

Using realpath -e /etc/resolv.conf should fix this. Please test the script in the fakeroot branch and continue discussion in #64
