[OpenWrt-Devel] [PATCH] [base-files] default_postinst() fix wrong call of group_add

[Bastian Bittorf]

[base-files] default_postinst() fix wrong call of group_add
after 12bae65d07d29854204715cebc1ef1eae237fd9b group_add is
always called. shell scripting can be tricky...

wrong call - stacked calls are wrong:
[ -n "$gid" ] && group_exists $name || group_add $name $gid

this leads to a call of 'group_add' when $gid is emtpy, proof:

root at box:~ [ -n "" ] && echo 'filled' || echo 'echo failed'
echo failed
