Package: initramfs-tools
Version: 0.89
Severity: wishlist

Hi maks,
When installing initramfs-tools in a chroot, I'd like to propose
that /etc/initramfs-tools/conf.d/resume not be created.
debian-live and other custom debian distributions build their system up in a
chroot environment, therefore it is not good for the resulting
initramfs-tools generated initial ramdisk to be configured for the system
that hosted the original chroot.
Plus, who can use suspend in a chroot environment? ;-)
Patch is attached. chrooted() function borrowed from udev's postinst.
Thanks, Kel.
