https://salsa.debian.org/ganeti-team/ganeti-instance-debootstrap/merge_requests/1 -- You are absolutely deluded, if not stupid, if you think that a worldwide collection of software engineers who can't write operating systems or applications without security holes, can then turn around and suddenly write virtualization layers without security holes. - Theo de Raadt

This is kind of important because that's how ping(8) works for regular users. We shove --selinux and --acls in there while we're at it, because why not. We never know what the future might bring, and it seems silly *not* to create a complete archive. Note that --xattrs-include='*' is important because, by default, GNU tar will not include capabilities /even/ if --xattrs is specified on the commandline, see this bug report for details: https://bugzilla.redhat.com/show_bug.cgi?id=771927 --- create | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/create b/create index 607bab2..7526e71 100755 --- a/create +++ b/create @@ -83,7 +83,7 @@ if [ "$CLEAN_CACHE" -a -d "$CACHE_DIR" ]; then fi if [ -f "$CACHE_FILE" ]; then - tar xf "$CACHE_FILE" -C $TMPDIR + tar --acls --selinux --xattrs --xattrs-include='*' -x -f "$CACHE_FILE" -C $TMPDIR else if [ "$PROXY" ]; then export http_proxy="$PROXY" @@ -109,7 +109,7 @@ else if [ "$GENERATE_CACHE" = "yes" ]; then TMP_CACHE=`mktemp "${CACHE_FILE}.XXXXXX"` - tar cf "$TMP_CACHE" -C $TMPDIR . + tar --acls --selinux --xattrs --xattrs-include='*' -c -f "$TMP_CACHE" -C $TMPDIR . mv -f "$TMP_CACHE" "$CACHE_FILE" fi fi -- 2.20.1
