Optimisation: Automate checking for multilib on arch *solved*

[TN-1]

case $CHOICE in
        1)
            archlinux-2 &&
            select-your-path
            ;;
        2)
            sudo echo "[multilib]" >> /etc/pacman.conf &&
            sudo echo "Include = /etc/pacman.d/mirrorlist" >> /etc/pacman.conf &&
            archlinux-2 &&
            select-your-path
            ;;
esac

The above step could be replaced by a well crafted if and grep statement, checking if the multilib line exists and is uncommented. If so, archlinux-2. If not, then prompt the user to confirm the change then archlinux-2.

In pseudocode:

IF(grep[/etc/pacman.conf] for "multilib"[without #])
archlinux-2
else
dialog asking user to yes/no multilib

Happy to take care of this if nobody else (who actually use arch) wants to and if @cryinkfly approves the change.

I actually had this issue on my PC

fusion360-install.sh: line 488: /etc/pacman.conf: Permission denied

Didn't open github issue on it because I thought it was related to some of changes I had previously made to sudo on my system, but apparently same thing happened on fresh arch install in VM. I was going to further investigate the problem tomorrow and fix it, but keep that issue in mind when testing your upcoming changes :)

@blazej222 PR #101 implements a fix for that issue. See the link below for further info on the bug.
