为什么 /var/spool/abrt/ 文件夹没有被删除

Question

我们尝试删除所有 abrt 文件夹，如下所示（在 redhat Linux 机器上）

find /var/spool/abrt/*  -type d   -exec abrt-cli rm '{}' \;
rm '/var/spool/abrt/ccpp-2018-09-03-14:52:11-5653'
rm '/var/spool/abrt/ccpp-2019-03-26-12:18:52-31410'
rm '/var/spool/abrt/ccpp-2019-04-07-05:50:25-16907'
rm '/var/spool/abrt/ccpp-2019-10-29-14:20:46-20059'


pwd
/var/spool/abrt

但我们仍然看到文件夹和文件夹内容为

ls -ltr  /var/spool/abrt
total 24
-rw-------  1 root root   70 Nov  5 09:43 last-ccpp
-rw-------. 1 root root   48 Dec  9 03:25 last-via-server
drwx------  2 root root 4096 Dec  9 18:45 ccpp-2018-09-03-14:52:11-5653

drwx------  2 root root 4096 Dec  9 18:45 ccpp-2019-04-07-05:50:25-16907
drwx------  2 root root 4096 Dec  9 18:45 ccpp-2019-10-29-14:20:46-20059

为什么 abrt-cli rm不删除文件夹？

来自 abrt.conf

grep -v "^#" /etc/abrt/abrt.conf
