* New upstream snapshot. * move install log from /var/log/curtin_install.log to /var/log/curtin/install.log (LP: #1378910) * to not use '--acl' when extracting tar files (LP: #1382632) as it inadvertently writes default directory acls. * invoke lsblk with '--output' rather than '--out' to avoid ambiguity in newer versions of lsblk (LP: #1386275)
