I'm having trouble understanding why the test is checking
[ "$1" = remove ]
instead of
[ "$1" = upgrade ] || [ "$1" = install ]
Isn't this operation relevant on upgrade/install, instead of on removal?
My reasoning is: upgrade covers the normal upgrade path case. install
covers the case where an older package was earlier removed (not purged,
so the conffile is still present), and a newer version is being installed.
Why should preinst testing for "remove" here? What am i misunderstanding?
--dkg, confused as ever
