Subject: dracut-functions.sh: cp with --reflink=auto and --sparse=auto
X-Git-Tag: 020~50
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=d5b5bb310312fa2956cf9ff091aeeec84f1e6e6e;p=thirdparty%2Fdracut.git

dracut-functions.sh: cp with --reflink=auto and --sparse=auto

cp will use COW data copy most of the time. So, it's even better than
hardlink, because we don't have to care about hardlinks, when modifying
files in post.
