ACFS install on CentOS

I run CentOS on a test cluster, and every time I patch it with a PSU or whatever, my ACFS installation is trashed as CentOS is not officially supported.

To fix this, change the following section in $GRID_HOME/lib/osds_acfslib.pm…

  if ((defined($release)) &&                     # Redhat or OEL if defined
      (($release =~ /^redhat-release/) ||        # straight RH
       ($release =~ /^enterprise-release/) ||    # Oracle Enterprise Linux
       ($release =~ /^oraclelinux-release/)))    # Oracle Linux
  {

…to…

  if ((defined($release)) &&                     # Redhat or OEL if defined
      (($release =~ /^redhat-release/) ||        # straight RH
       ($release =~ /^enterprise-release/) ||    # Oracle Enterprise Linux
       ($release =~ /^centos-release/) ||        # CentOS hack
       ($release =~ /^oraclelinux-release/)))    # Oracle Linux
  {

…then re-run the ACFS install as root and you should be good to go.
