How to mount a 4.2 BSD file system ?

[ioops]

Hi all,

I would like to rescue a 4.2 BSD partition.

First I tried to mount the 4.2BSD filesystem from an FreeBSD 8.0 Install CD. But When I started the shell I got only the char " # " and no unix command was supported. I really didn´t understood this shell. Then I burned a FreeBSD live CD but the system didn´t boot. Maybe I donwload the wrong file ...

Then I used an Linux RIP CD. The UFS kernel module is loaded.

I did this :

fdisk -l /dev/hda :

/dev/hda1 ID=9f System=BSD/OS (bootable)

fdisk -l /dev/hda1 :

/dev/hda1p1 ID=ff System=BBT
/dev/hda1p2 ID=ff System=BBT
/dev/hda1p3 ID=72 System=Unknown

ls /dev/hd* :

/dev/hda
/dev/hda1
/dev/hdc (cdrom)

The live CD allow me to do some stuff on the HDD. The "List format of disk partitions" menu display :

Partition a : 24.12 MiB, Type 7 (4.2 BSD Fast File Format) Dos MBR partition
________ partition 1 : 3.605 GiB, Type 0x9f BSD/OS, UFS Last mounted at "/"
Partion b : 255.9 MiB, Type 1 (Swap)
Partition c : 3.605 GiB, Type 0 (unused)
Partition h: (4.2 BSD Fast File System) UFS, Last mounted at "/usr".

How can I mount the "/" partition ? If I don´t have any /dev/hda1px ? May I to create them with mknod ? How can I determinate the types Major and Minor ?
Can I do later an chroot command ?

Thanks a lot for your help.

Greatings.

You sure Linux RIP *safely* supports UFS?

I think it's better to use livefs. You should get it from the FTP.

Major and minor what?
Why do you need to chroot(8)? You do understand what it is used for?

Maybe I am confused about chroot. I used in previous cases to reconfigure some package. So I understood that I need to use the partition as a root.

About Major/minor I meant that I had to crate manualy the /dev/hda1p1.

I Downloaded the livecd and I was able to mount the partition and to correct what I did.

Thanks for your answer and your link.
