We can do it, using semanage commands, but not necessarily easy.

Currently regex match the default location of files stored on disk.


/srv/([^/]*/)?www(/.*)? system_u:object_r:httpd_sys_content_t:s0
/var/www(/.*)?  system_u:object_r:httpd_sys_content_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
/var/www/calamaris(/.*)?        system_u:object_r:calamaris_www_t:s0
/var/www/apcupsd/multimon.cgi   --
system_u:object_r:httpd_apcupsd_cgi_script_exec_t:s0
/var/www/apcupsd/upsimage.cgi   --
system_u:object_r:httpd_apcupsd_cgi_script_exec_t:s0
/var/www/apcupsd/upsstats.cgi   --
system_u:object_r:httpd_apcupsd_cgi_script_exec_t:s0
/var/www/apcupsd/upsfstats.cgi  --
system_u:object_r:httpd_apcupsd_cgi_script_exec_t:s0
/var/www/cgi-bin/cgi    --
system_u:object_r:httpd_mycgi_script_exec_t:s0


We could start to build tools that would allow you to change this location.


semanage fcontext -a -t httpd_sys_script_exec_t /srv/web/cgi-bin(/.*)?

Would add a context to this path.

system-config-selinux has graphical tools to do this, but it still
involves users choosing contexts and file paths.
