[et-mgmt-tools] Re: Cheetah raw/endraw (was: Templating...)

[Aaron Lippold]

Hi,

This looks perfect, since, if I was going to use placeholders, it
would most likely be before the post section, and if I do need to use
them I can use them at the top of %post, like MYVAR=$myvar .... then
use #raw and I can still access ${MYVAR}

... I am thinking paths for /usr/sbin/,/sbin/, etc.... although my
guess is they won't move stuff again from RHEL5 -> RHEL6.

Thanks again,

Aaron
