Yes, you should always leave the creation of a partition and the initialization of file systems to the OS which will be using them. In this case, just make sure there is unallocated space. > Btw, does the unallocated space physically need to be at a stretch? (How) Does > the partition manager arrange the physical position of partitions? Yes, a partition is always a contiguous space (here: space not allocated yet). Partition managers like PartEd Magic simply re-arrange the values in the partition table. Later on, file systems need to reflect those changes, but this can also often be done from within PartEd Magic (check FreeBSD's "growfs"). But resizing partitions usually isn't that easy (especially when you already have several partitions). > As (nearly) always in the world of Free Software, I can (successfully) use > whichever partition manager I want for this, can't I? Yes, just make sure you have a backup. Really. A verified backup. Just in case. As I mentioned above, PartEd Magic is a good solution for this task. It can be run safely from a live system CD or DVD. I think it's also part of UBCD. > Or is efibootmgr more > suitable for this task? Don't confuse the boot manager with a partition editor. If you have UEFI working on your system, its boot manager will do. If not, Grub can also load FreeBSD in a more "traditional" partitioning setting - this depends on several things, such as UEFI or BIOS, GPT or MBR, ... :-) -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
