Subject: GRMLBASE/98-clean-chroot: execute resolvconf workarounds also for systemd
X-Git-Tag: v0.31.2~5
X-Git-Url: http://git.grml.org/?p=grml-live.git;a=commitdiff_plain;h=3900f5d2c4f7c11478ecac404cd82b66b77564b9;hp=adae978839b766512c0f51aa41f37882beee8cf8

GRMLBASE/98-clean-chroot: execute resolvconf workarounds also for systemd

/etc/resolvconf/resolv.conf.d/original leaks data from the environment
the ISO was built in, and /etc/resolv.conf should be empty and be filled
with data from DHCP.

Thanks: András Korn
