Would love to get this fix ... I ran exactly into this problem.

Because dhclient.pid is nowhere else used in ReaR scripts
I assume changing the filename of the pid-file does not have
any unexpected bad side effects so that I approve this change.

I am not at all a DHCP expert but by plain looking at the code I wonder
why not the same fix is also needed for the IPv6 DHCP clients case in
usr/share/rear/skel/default/etc/scripts/system-setup.d/58-start-dhclient.sh

@gdha
if that fix is really only needed for the IPv4 case but not for the IPv6 case
could you then please add a comment at that code that explains why
both cases are different, cf. "Code should be easy to understand" at
https://github.com/rear/rear/wiki/Coding-Style
