+
+many solutions:
+
+- make an install on drive hdb, then either
+ 1. dd if=/dev/hdb of=/dev/hdc
+ 2. dd if=/dev/hdb of=/dev/hdc count=1 ; kernel_reread /dev/hdc ;
+ mke2fs /dev/hdc1 ; mount /dev/hdb1 /source ; mount /dev/hdc1 /dest ; cp -a /source /dest
+
+- try the oem feature
+ 3. - burn a cd out of *latest* cooker
+ - boot on it telling "oem" to syslinux
+ !! it will destroy every data on the harddrive !!
+ - you now have a very automated install matrix
+ (duplicate it with "dd if=/dev/hdb of=/dev/hdc bs=1M count=730")
+
+ put the harddrive in the oem box, the user will now have an *very* automated
+ install, just asking the root password and user password.
+
+ 4. (just like 3. without burning a cd, doing the first part by hand)
+ have a look at the /etc/oem script on the rescue and do it by hand...
+
+
+cu Pixel.
+
+
+comments:
+1. maybe copy unnecessary things -> take too long
+ solution -> use bs=8k count=xxxx
+2. kernel_reread can be found on the new rescue, source is also at end of this
+mail. This solution works with one partition. Can be easily enhanced to many
+primary partitions... For extended partitions, more complicated, but not much :)
+3. has just been added in latest cooker. It may still have some pb. The main
+current limitation is IDE only, though it can be fixed easily for special cases.
