From 8ef50277fc5530f60a910badd8d46478f6fd160e Mon Sep 17 00:00:00 2001 From: unknown Date: Thu, 25 Jan 2007 17:51:21 +0100 Subject: For Linux systems running RHEL 4 (which includes SE-Linux), we need to provide additional files that specify some actions which are allowed to the MySQL binaries. Create a new subdirectory "supportfiles/RHEL4-SElinux" for them, and process it. This fixes bug#12676. configure.in: New "support-files/RHEL4-SElinux/Makefile.am" must be processed by "automake" etc. support-files/Makefile.am: For Linux systems running RHEL 4 (which includes SE-Linux), we need to provide additional files that specify some actions which are allowed to the MySQL binaries.
