You have to do it exactly correct.  "./xxx" won't work; "/xxx" won't work,
it has to be exactly " . /xxx"

It's existed on Unix for many decades.

Here's an example from a 4.4 system showing how it works.

  bash-3.00$ cat x
  bash-3.00$ echo $VAR

  bash-3.00$ VAR=original
  bash-3.00$ echo $VAR
  bash-3.00$ . x
  bash-3.00$ echo $VAR
  bash-3.00$ cat /etc/redhat-release
  CentOS release 4.4 (Final)

So basically in the original, /etc/sysconfig/desktop consists of a line like
and the system works as expected.
