insert server name in position 1 on each line

Hello,
It has been a long time since I have written unix code and I need to insert a variable into the first position of each line in a file. Below is an example of the script and the desired output file

Here is my short script

server="$(hostname)"
df -kg | awk '{print $1, $2, $3, $4, $5, $6, $7}' > mountpoint.dat

Here is the contents of mountpoint.dat
/Filesystem GB blocks Free %Used Iused %Iused
/dev/hd4 0.25 0.09 63% 6496 23% /
/dev/hd2 4.00 2.07 49% 44947 9% /usr

I need the output in the following format for each line

server/Filesystem GB blocks Free %Used Iused %Iused
server/dev/hd4 0.25 0.09 63% 6496 23% /
server/dev/hd2 4.00 2.07 49% 44947 9% /usr

Thanks for your help!

df -kg | awk '{print "server" $1, $2, $3, $4, $5, $6, $7}' > mountpoint.dat

Regards

To use the hostname as variable:

df -kg | awk -v server=$(hostname) '{print server $1, $2, $3, $4, $5, $6, $7}' > mountpoint.dat

Regards

Thank you so much, I see what I was missing in the awk command.
