Avoiding Typing Encryption Passphrase Multiple Times

[guix . rc7ys]

Hello,

I currently have both my root and home partition encrypted with the same 
passphrase. However, I have to type the same passphrase four times, the two 
partitions while in initial ram disk and then again after the initial ram disk 
boots the operating system.

Is there a way to only have to type the passphrase once? Any guidance would be 
greatly appreciated.

Regards,
John
