Re: rwd0a and label sector marked read-only

All partitions (except RAW_PART) are defined in the disklabel,

the disklabel is updated via a partition which is being changed.
- why EROFS and not EPERM?
Because it requires a proper procedure (DIOCWLABEL), not privilege?
Well, disklabel(8) mentions for -W option:
"Allow writes to the disk sector that contains the label."
For me "allow/disallow" is more tied to a permission than a read/write
state, that's why I am asking. But I am no native speaker :)
Besides, returning EROFS might be misleading for the user, as it informs
that the fs is read-only, which is partly correct here (having one
sector marked read-only does not necessarily mean that the rest is in
the same state).
Thanks for the answers.
