Should the container rootfs take the input Type instead of hardcoding ext4?

Line 1186 in e6c7a36

rootfsMnt.Source, vmBundleDir.RootfsPath(), "ext4", nil, s.driveMountClient, s.machine)

I'm specifically interested in supporting XFS-based snapshots for the container rootfs. I know other drives can be XFS, is there a reason that the container rootfs has to be ext4? (Assume I build my kernel with XFS support)

Thanks!

Hi @ctrlaltdel121 thanks for raising this issue. I like this idea to make the FS type configurable. Feel free to submit a PR and we'll be happy to review it.
