There are packages that need to add/remove inetd entries on
install/uninstall. This is easy with xinetd, but AFAIK
Red Hat itself recommends to develop on older systems
to ensure maximal compatibility right now due to
Is there a recommended future-proof way to check, whether
there is inetd or xinetd running on the target machine?
I would say that a wrapper similar to chkfontpath,
chkconfig etc. should be used - this does not solve anything
for previous releases, but might help if there is similar
change in the future.
There isn't a glibc/compilers mess, but binaries compiled on 7 aren't compatible
with 6.2 due to use of new glibc (binary compatiblity is what we use to define a
major series). 7 is a nice development platform, but if you need to deploy on
multiple releases you need to compile with older libraries as the other ones
aren't as uptodate yet.
Anyway, inetd and xinetd are very different - the way to check for which one is
present would be "rpm -q inetd" (or xinetd), and check if it is running with
"service xinetd status" (or inetd)
