No - sysinst doesn't do that.
It creates a single mbr partition that covers (typically) sectors 63 on
and makes that bootable.

If you remove the mbr and put the pbr bootcode into the mbr (ie have the
root filesystem starting in sector 0) then you generate a disk that
is unbootable on some systems (because the bios validates the mbr)
and may cause problems with odd bios features which are known to use
other parts of track zero.
