default_postinst() fix wrong call of group_add
[base-files] default_postinst() fix wrong call of group_add after 12bae65d07d29854204715cebc1ef1eae237fd9b group_add is always called. shell scripting can be tricky... wrong call: [ -n "$gid" ] && group_exists $name || group_add $name $gid this leads to a call of 'group_add' when $gid is emtpy, proof: root@box:~ functionA() { echo A; } root@box:~ functionB() { echo B; } root@box:~ VAR= root@box:~ [ -n "$VAR" ] && functionA || functionB B root@box:~ # functionB was called, but VAR is not filled root@box:~ VAR=filled root@box:~ [ -n "$VAR" ] && functionA || functionB A Signed-off-by: Bastian Bittorf <bittorf@bluebottle.com> git-svn-id: svn://svn.openwrt.org/openwrt/trunk@42926 3c298f89-4303-0410-b956-a3cf2f4a3e73
