Script to resize embedded images
-
Hi,
New in this Forum, i say hello to everyone interested.
I have recreate a skript to create 128, 256, 512 or 1gb Images out of the original 64mb embedded one.
Works only on FreeBSD, feel free to modify it for Linux.How to use:
Save skript in your homedir.
#> mv mkflash_new.txt mkflash_new.sh
#> chmod +x mkflash_new.sh
Download latest Snapshot from http://www.pfsense.com/~sullrich/
Get pfSense.img.gz from there and place it in your homedir
Unpack pfSense.img.gz with
#> gzip -d pfSense.img.gz
Be shure to get root-rights
#> su
execute skript like:
Usage: /home/marcel/mkflash_new.sh {128|252|512|1024} {Originalimage}
Example: #> /home/marcel/mkflash.sh 128 /home/marcel/pfSense.imgVoila, take a look on the new image-file:
pfSense-128MB.img.gz
pfSense-128MB.img.gz.md5Have fun,
Marceledit: changed heading to resize image….

It seems there is no support fpr Memory Disks on your System.
Does a```
#> kldload /boot/kernel/geom_md.ko -
-
The Sourceimage has to be decompressed FIRST!
Use```
#>./mkflash_new.sh 256 pfSense.img -
I'm very sorry!
I forgot gunzip the image file before running the script …
Many thanks!
