cp /var/lib/dhclient/dhclient.leases /sysroot/dev/.dhclient-$dev.leases

mkinitrd for a while has copied the leases file to /dev, because it is the only directory that survives switch_root. The system then can have the entire leases file for whatever needed purposes.

Any objections to doing this in dracut?

None here. We should do something along those lines for /tmp if we were asked to debug the initrd.

None here. We should do something along those lines for /tmp if we were asked to debug the initrd.

If netboot, copy /tmp/net.* for the boot interface to /dev/.boot/

This is for the use of anything in the booted system that needs to be aware of what network was brought up during initrd.

If cmdline rdcopystate, then copy all of /tmp/* into /dev/.boot/

This is primarily for debugging purposes.

Thoughts?
