mkfs. any way to personalize the uuid generation?

0

Running mkfs.<type> [...] generates a File System and its UUID. any way to personalize it? In a fashion like "not generate UUID with numbers '4' and '5' or letters 'b' 'c' ".

man mkfs:

   -U UUID
          Set the universally unique identifier (UUID) of  the  filesystem
          to UUID.  The format of the UUID is a series of hex digits sepa‐
          rated          by          hyphens,          like          this:
          "c1b9d5a2-f162-11cf-9ece-0020afc76f16".   The UUID parameter may
          also be one of the following:

               clear  clear the filesystem UUID

               random generate a new randomly-generated UUID

               time   generate a new time-based UUID

There is no mkfs. There are mkfs.<type>. Each of them on its own may or may not support -U and the option may or may not mean what you wrote. E.g. compare what man mkfs.ntfs says about -U. – Kamil Maciorowski – 2018-11-13T13:23:30.710
