What is "MTBR"? |

I'll assume you mean MBR. |

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

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. |

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.). |

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. |
