* BIG FIXME!!
|
|
* ===========
|
|
*
|
|
* All that stuff *MUST* go into the fsutil.c module.
|
|
* Indeed, all that relates to filesystem formatting details and as such
|
|
* *MUST* be abstracted out from this module (bootsup.c).
|
|
* However, bootsup.c can still deal with MBR code (actually it'll have
|
|
* at some point to share or give it to partlist.c, because when we'll
|
|
* support GPT disks, things will change a bit).
|
|
* And, bootsup.c can still manage initializing / adding boot entries
|
|
* into NTLDR and FREELDR, and installing the latter, and saving the old
|
|
* MBR / boot sectors in files.
