如何在 CentOS 上的 audit.log 中修复这个 dovecot SELinux 错误？

我在/var/log/audit/audit.logfor中收到这些 SELinux 错误dovecot。

我试过了

# sealert -a /tmp/dovecot5.log
100% donefound 1 alerts in /tmp/dovecot5.log
--------------------------------------------------------------------------------

SELinux is preventing /usr/libexec/dovecot/imap from read access on the directory starrychloe.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that imap should be allowed read access on the starrychloe directory by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep imap /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

然后

# cat /tmp/dovecot5.log | audit2allow -M dovecot
******************** IMPORTANT ***********************
To make this policy package active, execute:

semodule -i dovecot.pp

哪个产生了

# cat dovecot.te

module dovecot 1.0;

require {
        type dovecot_t;
        type home_root_t;
        class dir read;
}

#============= dovecot_t ==============
allow dovecot_t home_root_t:dir read;

但是我收到了这个错误

# semodule -i dovecot.pp
libsepol.print_missing_requirements: dovecot's global requirements were not met: type/attribute dovecot_t (No such file or directory).
libsemanage.semanage_link_sandbox: Link packages failed (No such file or directory).
semodule:  Failed!

这些是目录的权限

# ls -dZ /home/starrychloe
drwxr-xr-x. starrychloe starrychloe unconfined_u:object_r:home_root_t:s0 /home/starrychloe

我正在使用 CentOS 6.5。
