Feature request: option to resize partitions/filesystems on disk to fill available space

• Etcher version: All
• Operating system and architecture: All
• Image flashed: Raw disk images
• Do you see any meaningful error information in the DevTools? n/a

Use case for this feature request: I have a build process whose output artefact is a raw disk image with two partitions. This image then gets flashed onto boot media of various sizes. Since the size isn’t known ahead of time, the image can’t be pre-sized to the boot media. That means the process for flashing looks like this, resizing the partition with parted and then the filesystem with e2fstools:

etcher my-image.img # or dd if=my-image.img of=/dev/sdX if you're feeling dangerous
parted -s /dev/sdX resizepart 2 '100%'
resize2fs /dev/sdX2

Could this be implemented as part of Etcher? For the UI, perhaps a check-box for ‘Attempt to maximize partition size’, and a similar command line option?

Syncloud project is willing to pay for this feature £100 even if it is a Linux only option, job proposal is published at upwork.com

I’m fairly sure we discussed this before somewhere, but Github search isn’t finding the right issue discussion for me…

Etcher simply copies the disk image byte-perfect onto the destination drive, and doesn’t mess about with the partition tables at all. So I dunno if we’ll be adding this feature anytime soon. In the meantime, perhaps you could use the same workaround that Raspbian uses, where it automatically enlarges the root partition the first time it boots up?
