Duplicate partition table in ubuntu

Note: Haven't got chance to test this.

Duplicate partitions

sfdisk -d /dev/sdX > part_table
sfdisk /dev/sdY < part_table

This will keeping the same disk & partition IDs, mainly for backup and restore partition purpose.

Generate new partition IDs

grep -v ^label-id part_table | sed -e 's/, *uuid=[0-9A-F-]*//' | sfdisk /dev/sdY
