I've developed a script and suitable grub stanzas to let the user install several CD-ROM images on a hard drive, and boot from the CD-ROMs without extracting the kernel or initrd. This gives the user something of a rescue capability without requiring a CD/DVD or thumb drive.
The three images I have been working with are recent netinst weekly builds, a recent Finnix, and the gparted live CD. All three go on their own partition, in hope that that partition would isolate them from file system catastrophes. I think this might make a useful how-to, possibly for the Debian wiki. Any thoughts on where to contribute it? -- Does anybody read signatures any more? https://charlescurley.com https://charlescurley.com/blog/
