I found a similar-sounding problem for partman-efi - the wrong GUID
was being used there too. AFAICS recent parted versions default to
using the "Windows Basic data partition" GUID and you need to tell
parted to do things differently if you want different behaviour. For
UEFI, adding "write_line esp" helped (commit
7ce58763e8f1766ad5461b9be73fe961d9bbf4e3 in partman-efi). I'm not sure
if something similar will help you...
