You can build a Linux kernel, I'm pretty sure, that will support the SCO file system.

Also, see this web discussion.

Quote:

For now you can do the following:
simply create a SCO filesystem on a raw partition manually, Linux will be
able to mount that filesystem, and so will SCO.

"mdev hd" is a script that runs fdisk, then divvy, then mkfs (among other
things)

The easiest way to go would be to run mkdev hd to add a new hard drive,
(this creates the /dev/hdxxx device files for you) then determine the
device name for your new raw partition (or whole drive for that metter,
you actually do not need any partitions at all, not even one that takes up
the whole drive)

then dd if=/dev/zero of=/dev/hd10 (for whole 2nd ide drive for instance)
then mkfs -f HTFS /dev/hd10
then mkdir /d2
then mount -f HTFS /dev/hd10 /d2
then to copy your "u" filesystem,
cd /u; tar cf - . | (cd /d2 ;tar xf -)
then in Linux:
mkdir /d2
modprobe sysv
mount -t sysv /dev/hdb /d2

Note: if Linux can't read the HTFS filesystem, you may need to try
substituting one of the following until it works. I know for a fact Linux
reads Xenix just fine, but Xenix fs has yucky limitations like 14
character name length

AFS Acer Fast Filesystem
DTFS Desktop Filesystem
EAFS Extended Acer Fast Filesystem
HTFS High Throughput Filesystem
S51KB AT&T UNIX(R) System V 1KB Filesystem
XENIX XENIX(R) filesystem

Unix user ID's case-sensitive?

It has been quite a while since I used UNIX. I am developing a security system and I was wondering if UNIX and/or LINUX user ID's are case-sensitive. i.e. can user 'daveb' and 'Daveb' exist on the same system with completely different authorizations/priorities, etc.?

NAME

       hd - MFM/IDE hard disk devices

DESCRIPTION

       The  hd*  devices  are block devices to access MFM/IDE hard disk drives in raw mode.  The master drive on the primary IDE controller (major
       device number 3) is hda; the slave drive is hdb.  The master drive of the second controller (major device number 22) is hdc and	the  slave
       hdd.

       General	IDE block device names have the form hdX, or hdXP, where X is a letter denoting the physical drive, and P is a number denoting the
       partition on that physical drive.  The first form, hdX, is used to address the whole drive.  Partition numbers are assigned  in	the  order
       the  partitions	are  discovered,  and only nonempty, nonextended partitions get a number.  However, partition numbers 1-4 are given to the
       four partitions described in the MBR (the "primary" partitions), regardless of whether they are unused or extended.  Thus, the first  logi-
       cal  partition  will be hdX5.  Both DOS-type partitioning and BSD-disklabel partitioning are supported.	You can have at most 63 partitions
       on an IDE disk.

       For example, /dev/hda refers to all of the first IDE drive in the system; and /dev/hdb3 refers to the third DOS "primary" partition on  the
       second one.

       They are typically created by:

	      mknod -m 660 /dev/hda b 3 0
	      mknod -m 660 /dev/hda1 b 3 1
	      mknod -m 660 /dev/hda2 b 3 2
	      ...
	      mknod -m 660 /dev/hda8 b 3 8
	      mknod -m 660 /dev/hdb b 3 64
	      mknod -m 660 /dev/hdb1 b 3 65
	      mknod -m 660 /dev/hdb2 b 3 66
	      ...
	      mknod -m 660 /dev/hdb8 b 3 72
	      chown root:disk /dev/hd*
