This sounds pretty interesting !
However, on which version is it available?
https://bugzilla.redhat.com/show_bug.cgi?id=861250 seems to mention that RHEL6 has it, but maybe not first versions of RHEL ...
is there a way to detect if the feature exists ?

According to http://illiterat.livejournal.com/8221.html the --setopt option was only introduced in RHEL 6.1's yum.

However, that option is just a wrapper to make it possible to change config values from yum.conf on the command line. So maybe we can set it via yum.conf (or a temporary yum.conf) before that version...

However, according to http://lists.baseurl.org/pipermail/yum-devel/2010-June/007087.html, it seems that the "exit_on_lock" option was only added after --setopt, so no.

But I have found a solution: yum versions without the --setopt option complain when it is used, and yum versions with it but when passed a specific option that is not in the main config, it complains too. So by running:

yum --setopt=exit_on_lock=True 2>&1 | grep -E "(Command line error: no such option: --setopt|Main config did not have a exit_on_lock attr. before setopt)" 

If the command returns 0, that means the option is not supported.

Note: this works even if yum's lock is already obtained, because there is no yum command (so the first command will return 1, and not even try to take the lock)

Make sure to export LANG=C first so we don't have * localised error messages
