Right.

Also something more simple: I'd like to have ll='ls -la' on my systems
and OpenWRT based "mini-distributions". Right now I have to change
package/base-files/etc/profile or override /etc/profile completely from
the files/ folder. In this case it's not too complicated, but its not
maintainable very well.

Another maybe more interesting example is the Java VM "jamvm". It
depends on "classpath" which is quite big and one of my systems has to
be installed on the SD card. Because the libraries are on /mnt/sd/ I
need "export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/mnt/sd/usr/lib/classpath"
for jamvm to work properly. That could go into a "system" and
"distribution" specific package which puts it into /etc/profile.d/...
which is much cleaner than overriding /etc/profile or -worse- messing
with /etc/profile in a postinst script...
