https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=295062 Bug ID: 295062 Summary: nuageinit fails for non-YAML user-data scripts Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: bin Assignee: bugs@FreeBSD.org Reporter: ross@exitzero.uk nuageinit(7) provides support for cloud-init (https://cloud-init.io/) to allow customisation of FreeBSD disk images on first boot. "BASIC-CLOUDINIT" images are built as part of the FreeBSD release process, with nuageinit configured to run on first boot. On previous FreeBSD releases (I have tested on 14.3 and 15.0), the "user-data" (or "user_data") file could be provided as a YAML file, with the first line reading "#cloud-config" (note there is a typo in the man page, which incorrectly specifies "#!cloud-config") or as an executable script, with a shebang like "#!/bin/sh -e". Historically, YAML support was quite limited and so I needed a shell script to provide my required functionality. Unfortunately, support for executable scripts is broken in CURRENT, 14.4-RELEASE and 15.1-RELEASE (awaiting beta testing at time of writing). The bug is in /usr/libexec/nuageinit (https://cgit.freebsd.org/src/tree/libexec/nuageinit/nuageinit) introduced in this commit: https://cgit.freebsd.org/src/commit/libexec/nuageinit/nuageinit?id=cae280931c9e1f072d8bf300c377ae120300b898 On line 732 (https://cgit.freebsd.org/src/blame/libexec/nuageinit/nuageinit?id=cae280931c9e1f072d8bf300c377ae120300b898#n732) the load_userdata() function attempts to parse the user-data file as YAML, then failing and exiting if that parsing is unsuccessful. Unfortunately, the check for whether the file contains YAML or not doesn't occur until line 760 (https://cgit.freebsd.org/src/blame/libexec/nuageinit/nuageinit?id=cae280931c9e1f072d8bf300c377ae120300b898#n760), which is run after the load_userdata() function has been called. It is therefore never possible to reach line 793, where a non-YAML, executable user-data file is handled. Possible workaround: Switch away from an executable user-data to YAML. I don't believe this will meet all my requirements since my existing script explicitly sets group IDs, which isn't supported in the YAML version. -- You are receiving this mail because: You are the assignee for the bug.home | help
