Create ramdisk for rescue

Feature state

openSUSE Distribution
Rejected Information

Description

Create ramdisk for rescue filesystems. This ramdisk could been placed in /boot, other separate partition or root filesystem. There also should exist option for run system from this ramdisk.

This could been integrated with systemd in future. When systemd fail load system, it should create ramdisk, copy rescue tools onto it, chroot and unmount old root filesystem(if possible, I'm not kernel developer).

Usecase

On laptops without CDrom, there's should exist way to rescue system. Sometimes filesystem must be repaired, because badblocks were created.

any PC with openSUSE installed have a boot way to an iso, dvd (may be usb dvd), usb or else.

I don't either understand the description, a ram disk is in ram, not on a partition??

Search information about Linux initial ramdisk. Linux on boot sequence decompress file placed on some partition (/ or /boot) and use it as ramdisk. After this step, scripts on this ramdisk mount root filesystem and chroot onto it.

My idea was created for laptop without CD drive or for users, who downloads live distribution.
