Você pode impedir que isso aconteça usando o UUID no lugar dos caminhos dos dispositivos.
Seu fstab deve ser parecido com
# /etc/fstab: static file system information.
#
# Use 'blkid -o value -s UUID' to print the universally unique identifier
# for a device; this may be used with UUID= as a more robust way to name
# devices that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc nodev,noexec,nosuid 0 0
# / was on /dev/sda1 during installation
UUID=60db2d35-5065-476c-9396-92e8754dd613 / ext4 errors=remount-ro 0 1
# /home was on /dev/sda3 during installation
UUID=66d44124-3c90-4e42-8d1a-eb8f84350b4b /home ext4 defaults 0 2
# swap was on /dev/sda2 during installation
