Clear data and system in updater-script w/o clearing sdcard? - Android Q&A, Help & Troubleshooting

Every time I flash a ROM I'm playing with, using the clear data options I added, it clears the sdcard too?
I'm using this code with the AROMA installer:
Code:
# Clear Data
if file_getprop("/tmp/aroma/clear.prop","selected.1") == "1"
then
ui_print("@Wiping Data...");
delete_recursive("/system");
delete_recursive("/data");
delete_recursive("/preload");
endif;
ui_print("@Clearing Cache and Dalvik...");
delete_recursive("/cache");
delete_recursive("/data/dalvik-cache");
delete_recursive("/dalvik/dalvik-cache");
The only instance of format I have is here:
Code:
format("ext4", "EMMC", "/dev/block/mmcblk0p9", "0");
mount("ext4", "EMMC", "/dev/block/mmcblk0p9", "/system");
mount("ext4", "EMMC", "/dev/block/mmcblk0p12", "/data");
mount("ext4", "EMMC", "/dev/block/mmcblk0p7", "/cache");
run_program("/sbin/mount", "/dev/block/mmcblk0p12", "/dalvik");
run_program("/sbin/busybox", "mount", "/sdcard");
Which is confusing me a lot

Bump
Can someone please shed some sort of light as to why this deletes the contents of the SD card?
Is it possible to clear system and data within an updater-script WITHOUT killing my internal sd card?

---

I think its the
Code:
delete_recursive("/preload");
line thats doing it - i don't have that line, neither do any of the other Roms updater scripts that ive looked at
Remove it and see what happens

Such an old thread, just trying my luck.
How were you able to run the function "delete_recursive" in updater-script?
I dont see it as part of the official functions list.

Write such a function at your own
Syntax
delete_recursive <file-or-dir1> [... <file-or-dirN>]
Example
Code:
delete_recursive()
{
for d in "[email protected]"; do rm -rf "$d" 2>/dev/null; done
}

Hey, thanks for the response.
But how will I be able to run these functions as part of the updater-script?
And also, regular unix commands like ls, rm are not available in recovery.

1. You add these lines of code to the very beginning of the updater script, but after the line #!/sbin/sh or similar one
2. Recovery ( at least the Stock Recovery ) merely is a menu what offers you some options, it's not an Android terminal
