Update updateip.sh

[kawaiipantsu]

updateip.sh breaking on Debian OS installs where multiple partitions are present

Make sure to target root partition, Debian will often come with /boot/efi or similar. This little hack will utilize regular expression to match line starting with / but having a blank after. So only root partition should match.

Example:

# lsblk -o MOUNTPOINT,UUID
MOUNTPOINT UUID

/          xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx

/boot/efi  7034-6125


# echo "TEST_BEFORE=$(lsblk -o MOUNTPOINT,UUID | grep -e "/" | awk '{ print $2 }')"
TEST=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
7034-6125

# echo "TEST_FIXED=$(lsblk -o MOUNTPOINT,UUID | grep -e "^/ " | awk '{ print $2 }')"
TEST=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx

Where i'm guessing the last outcome is the desired outcome. I think this change will help you in the long run to be more compatible with systems that have multiple partitions.
