[bug#75027] [PATCH 0/3] 'guix system reconfigure' loads system for kexec reboot

[Ludovic Courtès]

Hello Guix,

Following work by Jakob Kirsch adding kexec support in the Shepherd
(the new ‘reboot -k’ option), here’s the Guix side of it: with these
patches, ‘guix system reconfigure’ loads the new system so that one
can run ‘reboot -k’ to quickly reboot into it.

Thoughts?

Ludo’.

PS: It took me a while to debug until I realized it was working
    very well: it’s just that I was booting a kernel with “quiet”
    on its command line, so I couldn’t see anything. 🤦

Ludovic Courtès (3):
  syscalls: Add ‘kexec-load-file’.
  system: Export ‘…-initrd-file’ and ‘…-root-file-system’.
  reconfigure: Call ‘kexec-load-file’.
