Is there any pointer to best practices for packing a web application

The Packaging Guidelines mention Web Applications, but not how to make
them work with SELinux:
https://fedoraproject.org/wiki/Packaging/Guidelines#Web_Applications
Do you already have the policy for your webapp written?
If so, you can proceed according to
https://fedoraproject.org/wiki/SELinux_Policy_Modules_Packaging_Draft
but better still would be to post your policy on fedora-selinux-list for
comment and get it merged into the main Fedora policy and upstream.
No policy yet. I think I just need file_contexts to go along with the
standard ones:
/srv/([^/]*/)?www(/.*)? system_u:object_r:httpd_sys_content_t:s0
/var/www(/.*)? system_u:object_r:httpd_sys_content_t:s0
/var/www(/.*)?/logs(/.*)? system_u:object_r:httpd_log_t:s0
/var/www/[^/]*/cgi-bin(/.*)? system_u:object_r:httpd_sys_script_exec_t:s0
/var/www/perl(/.*)? system_u:object_r:httpd_sys_script_exec_t:s0
/var/www/icons(/.*)? system_u:object_r:httpd_sys_content_t:s0
/var/www/html/[^/]*/cgi-bin(/.*)? system_u:object_r:httpd_sys_script_exec_t:s0
/var/www/cgi-bin(/.*)? system_u:object_r:httpd_sys_script_exec_t:s0
I found that Debian has pretty well-defined (draft) guidelines for web
applications:
http://webapps-common.alioth.debian.org/draft/html/
that standardizes on /usr/share/PACKAGE/www for static content and
/usr/lib/cgi-bin/PACKAGE for arch-dependent dynamically executed
content.
If we could come up with a similiar standard, then we could add
standard SELinux file_contexts to deal with it, such as:
/usr/share/[^/]*/www(/.*)? system_u:object_r:httpd_sys_content_t:s0
/usr/share/[^/]*/cgi-bin(/.*)? system_u:object_r:httpd_sys_script_exec_t:s0
/usr//lib(64)?/[^/]*/cgi-bin(/.*)? system_u:object_r:httpd_sys_script_exec_t:s0
That sounds good to me.
