Good time of the day, Andrei.
You worte:
Any suggestions?
Why don't You copy Your installation w/ "cp -a" and reconfiguring then
grub for the copy - to another disk (USB one?). OR I'm missing
something?
The Raspberry Pi can only boot from an SD card and the partition layout
matters (e.g. /boot needs to be primary, FAT32, bootable and probably
the first partition -- there is no bootloader like grub AFAICT).
# parted -l
Model: SD SD08G (sd/mmc)
Disk /dev/mmcblk0: 7948MB
Sector size (logical/physical): 512B/512B
Partition Table: msdos
Number Start End Size Type File system Flags
1 1049kB 79,7MB 78,6MB primary fat32 boot
2 79,7MB 336MB 256MB primary linux-swap(v1)
3 336MB 7947MB 7612MB primary ext4
The ext4 partition only holds about 630 MiB of data (Debian base install
+ SSH server). I want to create an image that I can:
* reuse myself later (just dd to some SD card)
* distribute to possibly not very knowledgeable people
Actually, I already have the image (with GNU ddrescue --sparse), but
it's about 5 times bigger than expected, which makes it difficult to
store and/or distribute :(
Hope this explains,
Andrei
So what you really need is a copy of the files on /boot and /. You don't
need the swap space and you don't need the empty space in the main
partition.
You can use fdisk to copy the partition information and a couple of cp
-a or tar's to copy the other files. You could even use dd to copy the
boot partition since it is pretty full. This could be put into a restore
script where you just need to identify the SD destination card.
However, unless the SD card is the same size, the main partition won't
fill the space.
