$ grep swap /etc/fstab

UUID=76f55d40-36cd-4f43-93e9-fd392beb26e5       swap swap       
defaults     0 0

UUID=7eb713dc-2bec-4c18-8c59-4094826feea8       swap swap       
defaults    0 0

Using the uuid of the device instead of it's device file name
in the GRUB_CMDLINE_LINUX line made no difference.
