I did something stupid and now don't know how to recover gracefully.
I intended to install a new kernel for use in a vm, but actually
installed the one for dom0 because I installed the wrong packagename.
The result is that Qubes does not boot but sends the machine into an
endless boot -> panic -> reboot ... loop.
The error message that flashes past says "tried to kill init" followed
by a dump of some kind that flicks past too fast to read
The docs tell me how to edit what file in order to correct the failure
to boot, at
but they do not tell me how to boot in order to issue the nano
command. I have also discovered that until Qubes 5 there is no plan to
bring in a boot menu with recovery options, as is provided for systems
still booting with grub2.
Am I right in assuming that until Qubes 5 there is no solution within
the Qubes system? Meaning that I will need to boot with Knoppix or
some other live distro ??
Or is there a more elegant route back to a working Qubes system?
If it is in the docs somewhere else, then please post a link to it
because I couldn't find it despite searching.
I think there should be slightly more in the docs than I could find
and am prepared to do the edit, but before I do that I want to know I
am making the most elegant suggestion.
I intend to update the docs in the section linked above sometime after
0500 UTC on 30th November and would welcome a heads-up by then if your
idea is more elegant that using Knoppix.
In the meantime, I am going to use Knoppix right now because a
solution I know beats an elegant one I didn't think of...
