grub2-mkconfig keeps detecting the same installation over and over

[Clemens Eisserer]

Hi,

I've just migrated my encrypted rootfs to a larger drive - after
changing UUIDs in a few places and recreating initramfs using dracut
everything seems to work fine again.

However, running brup2-mkconfig results in grub2 detecting my linux
installation over and over again:

grub2-mkconfig -o grub_try.cfg

Any idea what could possibly go wrong here?

Thank you in advance, Clemens
