The PAGER isn't compiled into the generated script; the script doesn't produce output requiring a pager. So it is strictly within the CLI that PAGER is used. When it comes to default settings, I generally don't change them except at a major release. As you have noted, another factor is that there is no uniformity with respect to the default pager implementation among the distributions. The current Shorewall philosophy is that distribution-specific settings are in the shorewallrc file. So we could add a new variable such as DEFAULTPAGER to the shorewallrc file and set it via the configure[.pl] script(s). Then, shorewall[6].conf could have PAGER=$DEFAULTPAGER. The only thing this buys is that installing straight from the tarballs can produce the same result as installing a distribution maintainer's package. Not sure if it is worth it. I'm copying the development list too for opinions on this issue, -Tom -- Tom Eastep \ When I die, I want to go like my Grandfather who Shoreline, \ died peacefully in his sleep.
