*.rpmnew exists iff the original file was locally modified wrto the md5
contained
within the old package metadata is what to watch out for.
Left over *.rpmnew can/will exist from previous upgrades, nuking *.rpmnew
is recommended and perhaps will simplify some logic, and avoid clock
skew issues.
inter-package existence tests like "-x /usr/sbin/selinuxenabled" are tricky
because when and where the scriptlet is run needs to be considered. You
might
just as well add a Requires: and rely on the transaction being ordered
correctly,
that is likelier to work predictably, and is a simpler script to write.
The whole scheme assumes that ${SELINUXTYPE} changes rarely, but
wot's a girl to do?
HTH Isn't rpm annoying? ;-)
