Modified:
trunk/debian/xserver-xfree86.preinst.in
Log:
debian/xserver-xfree86.preinst.in: migration-from-debconf-"management"
logic fixes:
- remove redundant test for existence of X server symlink
- base migration of existing X server symlink on the value of
shared/default-x-server being the same as the package being upgraded,
and the server symlink actually pointing to the server executable
provided by the package; do not pay any attention to the value of
shared/clobber_x-server_symlink
- store the target of the X server symlink in a variable since we
reference it more than once
- don't show the user messages telling him we're not doing anything
