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
