I naturally tried using backslash to escape the quotes since that is
pretty much the standard in scripting, but that just resulted in the
backslash getting embedded into the result:
lineinfile: dest=/etc/mail/sendmail.mc state=present
regexp='SMART_HOST' line="define(\`SMART_HOST\', \`{{smarthost}}\')dnl"
generates: define(\\`SMART_HOST\', \\`mailgw-sin.go2uti.com\')dnl
When I researched this on the Internet, I found
this:https://github.com/dotmaster/toYaml/issues/1 Essentially, the proper
way to escape a quote is with another quote. Except that isn't quite
working either (example in my original post).
What I found out minutes ago is that it appears to be related to the OS
version. When I use this:
lineinfile: dest=/etc/mail/sendmail.mc state=present
regexp='SMART_HOST' line="define(`SMART_HOST', `{{smarthost}}')dnl"
it works perfectly when the target server is OEL6.5 but with OEL5.5 as the
target server it generates define(\`SMART_HOST',
\`mailgw-sin.go2uti.com')dnl.
So something in OEL5.5 wants to escape the backtick during processing,
but does not do that in OEL6.5.
I tried using the replace module instead:
replace: dest=/etc/mail/sendmail.mc regexp="^define.*SMART_HOST.*dnl$"
replace="define(`SMART_HOST', `{{smarthost}}')dnl"
and that works perfectly on both flavors of OS. I don't know why since the
replace value of the replace module is identical to the line value of the
lineinfile module. There is a bug someplace in the chain when OEL5.5 is
the target, but we don't build very many OEL5.5 servers anymore, so I don't
think I am going to lose too much sleep over this. What ever works, I
guess.
