No, but I can see accidentally putting in an @exec/@unexec line that has
unfortunate consequences. We (pkgsrc developers) are definitely far
Regarding the issue of whether the user should be notified, I think
INSTALL/DEINSTALL scripts should also tell the user when they are doing
something that permanently affects the state of the system, e.g. adding
new users, "rm -rf" directories, etc. Currently, I've written the
template INSTALL/DEINSTALL scripts to output these notifications for
exactly these cases. We should sweep pkgsrc for package-specific
INSTALL/DEINSTALL script extras that may also do these types of actions
and cause them to notify the user of what they are doing, and add a note
to the pkgsrc guide as well.

I'm working on changes to bsd.pkg.install.mk that will remove the need
to list directories that should be removed when a package is deleted.
When that is done, we should be able to remove all of these "rmdir" and
"@dirrm" lines from PLISTs, and leave the PLISTs containing only files.
It is unfortunate that the majority of the @exec/@unexec lines in
pkgsrc are of the form you note above, as it does make it hard to
separate the signal, e.g. "@unexec /bin/rm -rf /var/db/pkg" from the
noise. As I said, this will hopefully change very soon.
