I'm planning to have apt set PATH to a sane value for running
dpkg, so that maintainer scripts are executed in a sanitized
environment. That value will be:
PATH=/usr/sbin:/usr/bin:/sbin:/bin
The effect:
(1) There is no /usr/local, which prevents breakage from custom perl
or python installation
(2) /snap/bin is not included either. This means that packages migrating
to snaps will have to provide compatibility links (scripts?) in /usr
- IIRC, lxd already does so, I'm not sure about other libraries.
Together, this ensures that deb packages only talk to deb packages.
Thanks,
Julian
