Warning: You requested a partition from 100MiB to 14772MiB (sectors
204800..30253055).
The closest location we can manage is 100MiB to 14772MiB (sectors
204801..30253055).
Is this still acceptable to you?
Yes/No? y
Warning: The resulting partition is not properly aligned for best performance.
Ignore/Cancel? c

(parted) q
I specified an exact, very nicely aligned, value of 100MB (which parted
wants spelled as "mi"llion "b"its...). Yet it somehow got rounded into
something 512 bytes bigger -- not rounded to a KB nor even MB. It went
right only when I wrote that 100MB as "102400kib" rather than "100mib"
as in the first try.
Thus:
1. values in exact units such as MB ("mib") must not get rounded
2. if you round, you should do so to a number that's aligned to common
erase block sizes
Meow!
