How to make a remastering tool use space on another partition?

[Luluc]

Good thing you mentioned that. Can we update the kernel ourselves? How?

I've been thinking:

1. I'm used to having a complete copy of my / structure.
2. Updating that copy is very fast because I use rsync. It just updates whatever has changed.
3. It seems to me that quick-remaster copies everything from the current installation.
4. What if it could use a previous remaster as reference to just "update" it, rsync style? Maybe it would be faster.

3) No, it doesnt copy. it mounts , as you may notice that it starts almost immediately with creating the .squashfs.
4) So , not faster.

If it creates a completely new 01-filesystem.squashfs, it has to copy.

Can't it open/mount an existing 01-filesystem.squashfs file then update it with the changes? It's obvious that it doesn't currently do that.

Depends how you call it. Creating 01-filesystem.squashfs from a mountpoint, I wouldn't call it copying.

AFAIK you need to unsquash it first , make changes and then squash again.
