[xcat-user] CentOS 5 post-installation

[Egan Ford]

Yeah I see the problem.

When postage is run it uses $(osver) to assign OSVER, and then passes that
to postrules for processing postscripts.tab.  So in this case for CentOS 5
everything should be assigned rhel5 since that is the flavor.

BTW, in postscripts.tab you can pass arguments to syncdirs, e.g.:

OSVER=centos.* or OSVER=rh.* or OSVER=sles.* or OSVER=suse.* {
        syncdirs blah
}

OR:

NODERANGE=foo {
	syncdirs blah bleh bar/foo centos5/x86_64
}

If you use RH5 and CentOS5 you may have problems with this, but if CentOS
only then this will work without changes to any scripts.  Only problem is
that syncdirs will still try rhel5 first before your arguments.

The decision to lump CentOS5 under RHEL5 was to save time, for most they are
either a COS5 or a RHEL5 shop, not both.

The best solution would be to have both COSVER and OSVER available for all
post scripts.  With minor changes to postage and postrules that can be done.
Then postscripts.tab could be used with COSVER rules as well.  Some minor
changes to syncdirs and a few scripts would also be required.  E.g. syncdirs
should really use COSVER.

Let me know what you want to do long term.
