this is more a general question ... about a point that drives me crazy

these days its quite easy to extend a disk (vmware, whaever) - And it really complicated to extend the filesystem.

This is perhaps a question to SUSE itself:
why it is required to partition the disk? why the installer requires that? grub2 can boot from ext4,btrfs,...

the problem is that resizing a partition never(?) works without a reboot
For additional disks you can use lvm or mkfs on the whole disk ... but not with Yast. Why?

I dont want to say that, but under windows this is simple ... extend (vmware)disk -> disk-manager -> extend ... thats all
or ZFS ...

What do you think?

Perhaps it is possible to address this in future versions ...
