share initrd artifacts between generations #49982

Open hyperfekt opened 6 years ago

hyperfekt commented 6 years ago

Issue description

Currently, any change to the initial ramdisk creates a completely new initial ramdisks with all specified parts. For systems with /boot on their own partition, space for those images is limited and will require purging configurations once exceeded. Often enough, however, there is limited change in the contents of this ramdisk between different generations. I suggest sharing identical artifacts in the initial ramdisk between generations by separating them into their own segments and letting GRUB2 concatenate them together as required.

Thank you for your contributions.

This has been automatically marked as stale because it has had no activity for 180 days.

If this is still important to you, we ask that you leave a comment below. Your comment can be as simple as "still important to me". This lets people see that at least one person still cares about this. Someone will have to do this at most twice a year if there is no other activity.

Here are suggestions that might help resolve this more quickly:

  1. Search for maintainers and people that previously touched the related code and @ mention them in a comment.
  2. Ask on the NixOS Discourse.
  3. Ask on the #nixos channel on irc.freenode.net.
