7 What is "MTBR"?

11 I'll assume you mean MBR.

20 "on tmpfs" would do, in any case we understand what you mean.

29 There many partition management tools and it soon becomes subjective which one
30 is /better/ - usually it is the tool you are most familiar with. If you want
31 a GUI tool, GParted tends to be the go to tool although I've come across
32 others. Personally, 'sys-apps/gptfdisk' is my go to tool for partitioning
33 block devices, but parted and GParted will also perform the required task with
34 aplomb.

45 Yes, both partition table types are readable by modern OS' and suitable
46 partitioning tools. The GUID Partition Table disks are self-identifying, with
47 all partition information stored on the physical disk and in addition with a
48 long list of partition type identifiers more attuned to Linux usage (e.g. for
49 /home, /, swap, etc.).

60 What I would consider reasonable in the year of 2020 is to use GPT, which is a
61 more versatile and useful structure for partitioning disks, without the
62 restrictions and deficiencies of MBR tables. On the other hand if you have a
63 really old disk which you are not planning to repartition, I would consider it
64 reasonable to leave it alone with its existing MBR table and get on with more
65 important/interesting tasks.
