The openSuSE Timezone & Clock definition
The next screen sets up the system clock. The time zone can be selected by first choosing the region and then the specific time zone from the drop-down lists, or by just clicking on the map. When the mouse cursor hovers on the map for a second or two, a pop-up shows its location.
Here you can also select how the hardware clock in the computer is kept – if dual-booting with Windows, the hardware clock will be kept in local time, but if you are running only Linux, you can select the check box to keep the clock in UTC.
openSuSE Suggested Partitioning
The next screen is the initial suggestion for disk paritioning, automatically determined by the openSuSE installation process. I mentioned at the beginning that most Linux distributions will do this automatically; if I had not manually shrunk the Windows C: partition, the Linux installer would have done that at this point also.
However, I have found that the installers are often overzealous in reducing Windows, leaving very little free space in the C: partition. This can, of course, be corrected at this point as well, but if I am going to have to monkey with the specific values anyway, I would rather just do it all in advance.
The installer will recognize the EFI Boot partition and set it to be mounted to the correct location, without reformatting. If there is a linux-swap partition already (as I created above), it will recognize and use that.
It will create new partitions for the root file system and home file system. The root will be allocated a minimum size, and the rest of the free space on the disk will be allocated to the home file system.
If you don't want or need a separate home file system, just un-check that box and the suggested layout will be updated, home will be removed and the free space will be added to the root file system.
More advanced users cal select btrfs for the root and home file systems rather then ext4, and can choose to use LVM disk management rather than traditional partitions (both of these are beyond the scope of this brief overview). For many users the suggested layout will be acceptable, but control freaks can click Edit Partition Setup to adjust it.
openSuSE Customized Partitioning
This is the control-freak path, actually several steps from the previous screen shot.
First I un-checked the box for a separate home partition, then I clicked Edit Partition Setup to get into the Expert Partitioner.
I then deleted the root partition from the suggested layout, and put root on the 64GB partition I had created with gparted earlier.
The installer had already found and used the swap partition I had created, and the EFI Boot partition, so there was nothing else to do for those.
Of course it is unusual to leave a huge unallocated area on the disk, but I will be installing other Linux distributions to this system, so I am leaving the space for that.
