Hello Krutonium,
Short version: HIC SUNT LEONES - there are lions here, don't try it.
Long version: converting NTFS comes up relatively often, but is not supported for a long list of reasons.
One reason is that it's EXTREMELY slow.
Another is that it's limited to ~2TB due to missing support for ioctl(FS_IOC_FIEMAP) both in FUSE ntfs-3g driver and in Linux ntfs filesystem.
And there are other reasons to...
I tried to solve or work around the problems of NTFS conversion several times, and until now I did not succeed.
Regards,
Massimiliano Ghilardi

Everything looks fine up until this point:

I assume I should be concerned, so I am wondering what the best course of action would be here.

Thanks to your fstransform tool, I successfully converted my Kubuntu 24 release from XFS to ext4 on a 60GB NVMe partition. However, the operation changed the UUID, causing GRUB to fail and stop at the GRUB prompt. I fixed it by update the UUID, the steps are located here: https://askubuntu.com/questions/1519153/how-to-convert-os-partition-from-xfs-to-ext4/1519264
Additionally, could you add a tune2fs command at the end of your code to revert the partition to its previous UUID AND modify the FS inside the fstab to the new one (in my case ext4)? I believe this will resolve the issue I encountered. Thanks very much.
