Default Some questions about installation of OpenBSD

Some questions about installation of OpenBSD

The Linux+FreeBSD mini-HOWTO

The principles should be equally applicable to other systems bsd.

2.2 Drive and partition labelling in Linux and FreeBSD

If you have a Linux extended partition after your FreeBSD slice you're in for trouble, because most Linux kernels installation floppies are build without UFS support, they will not recognise the FreeBSD partitions inside the slice. What should have have been seen as (/dev/hda3 is the FreeBSD slice and /dev/hda4 is the Linux extended partition)

Partition check:
 hda: hda1 hda2 hda3 < hda5 hda6 hda7 hda8 > hda4 < hda9 hda10 >

is seen as:

Partition check:
 hda: hda1 hda2 hda3 hda4 < hda5 hda6 >

This can give you the wrong device assignment and cause the loss of data. My advice is to always put your FreeBSD slice after any Linux extended partitions, and do not change any logical partitions in your Linux extended partitions after installing FreeBSD! 
I would like put openbsd on a 3 primary partition (or slices in bsd) on hdd PATA.
The problem is that after i have Linux extended partitions.

Support Unix (UFS) and Free BSD (FFS) file systems on Linux

I have seen that i have support for ufs (however don't on default) but there isn't support for ffs.

Perhaps i have think a workaround for this problem but i'm not sure that is right.

I if don't put partitions bsd on /etc/fstab linux the problem is avoid?

Bye Ale
