Having four space characters as your password causes bless to fail with error 103

See original GitHub issue

Today when I was installing Asahi Linux i found when it was doing the boot volume stage that while my password was set to four spacebar characters it kept saying that it wasn’t correct, as seen below, i then changed it to 8 normal text characters and it worked fine, as seen below in the log:

Choose what to do:
  r: Resize an existing partition to make space for a new OS
  q: Quit without doing anything
» Action (r): r


We're going to resize this partition:
  APFS [Macintosh HD] (494.38 GB, 6 volumes)
  Total size: 494.38 GB
  Free space: 210.37 GB
  Minimum free space: 38.00 GB
  Minimum total size: 322.01 GB (65.13%)

Enter the new size for your existing partition:
  You can enter a size such as '1GB', a fraction such as '50%',
  or the word 'min' for the smallest allowable size.

  Examples:
  30%  - 30% to macOS, 70% to the new OS
  80GB - 80GB to macOS, the rest to your new OS
  min  - Shrink macOS as much as (safely) possible

» New size (min): 80%

Resizing will free up 98.88 GB of space.

Note: your system may appear to freeze during the resize.
This is normal, just wait until the process completes.
