** Description changed: - This means that software installed via snap isn't transparently + [Impact] + + * This means that software installed via snap isn't transparently available for units to use. As snaps are first-class citizens in Ubuntu, we should update the PATH. - Specifically, this is evident by e.g. $ systemd-run env. Or any other - daemons that spawn shell scripts (e.g. cloud-init metadata acquired - shell hooks, etc.). - - Since v232 systemd provides support for environment generators, snapd - should package/ship a snippet that injects the correct snapd path into - systemd environment. - - E.g.: - - $ sudo mkdir -p /usr/lib/systemd/system-environment-generators - $ printf '#!/bin/sh\nPATH=$PATH:/snap/bin\n' | \ - sudo tee /usr/lib/systemd/system-environment-generators/90-snapd - - Something similar can be done for user-environment-generators too. Note - that user-environment-generators can generate unique variables per user. - - Note please use /usr/lib path, as it appears that /lib/systemd path is - not working atm. Will check if that needs to be fixed up. - - systemd in xenial does not support system-environment-generators, thus - we probably need to upload a patch to change the DEFAULT_PATH compiled - in default there. + * When a generator started to be provided by systemd, it was recognized + that $PATH is not correctly set, nonetheless, due to an environment bug + that systemd generators run in. [Testcase] $ systemd-run /usr/bin/env $ journalctl -e | grep PATH Output should contain /snap/bin + + Output should contain a complete and a valid PATH, i.e. + PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin" or similar. + + [Regression Potential] + + * snapd generator was already fixed separately to cause no harm, when + running under a broken systemd. With the corrected environment, + generators will now run with a correct PATH out of the box. A slight + change of PATH will be observed by all generators, when running in + containers/initramfs-less boots. However most generators will not be + affected as they typically do not execute external binaries.
