Subject: BSD slice in an extended partition ?

Hello,

I was trying to install RH6.0 on my home machine, so I deleted wd0s3e
where I stored some BSD data (to get an entry for a bootable partition
in the partition table).

wd0s3e was 4G in size, so I used 80M for a / partition in wd0s3 and I've
created 3 partitions inside an extended partition (slot wd0s4 of the
partition table) : 128Megs linux swap, 1,8 G for linux data, then what
is left (2G) for FreeBSD.

figure :
<wd0s1 = FAT><wd0s2 = 3.1 slice><wd0s3=linux root>
<s5=linux swap><s6=linux /usr><s7=available>

The remaining slice (wd0s7) can be accessed as a DOS partition (the
example given is the FAQ applies and gives a 2G FAT partition), but I'd
prefer it as a BSD partition.
tfh# newfs_msdos /dev/rwd0s7
/dev/rwd0s7: 4248824 sectors in 531103 FAT32 clusters (4096
bytes/cluster)
bps=512 spc=8 res=32 nft=2 mid=0xf8 spt=63 hds=255 hid=8337798
bsec=4257162 bspf=4150 rdcl=2 infs=1 bkbs=2
tfh# mount_msdos /dev/wd0s7 /mnt
tfh# df /mnt

/dev/wd0s7    2124412        4  2124408     0%    /mnt
tfh# 

I've looked at disklabel(8) and fdisk(8), but I don't see much help :
disklabel -w wd0s7 auto fails with :
tfh# disklabel -w wd0s7 auto
disklabel: ioctl DIOCGDINFO: Invalid argument
disklabel: auto: unknown disk type
tfh# disklabel -w /dev/rwd0s7 auto
disklabel: "auto" requires the usage of a canonical disk name
disklabel: auto: unknown disk type

Do I need to create a new entry in /etc/disktab ? Is it simply possible
to use an extended partition for FreeBSD ?

	TIA

	TfH

BTW : my RH6.0 install is still not satisfactory, as I haven't ben able
to boot from the newly loaded partition (it seems the mkinitrd phase was
not successful) - has anyone been able to make a full install, directly
from the 'Net, without loading the RPMs in advance ?
