* reboot: fix openlog(3) callsRicardo Branco2026-07-081-5/+5
| | | | | | | | | | | LOG_CONS was OR'd into the facility argument instead of logopt, leaving logopt as 0. The correct call is openlog(ident, LOG_CONS, LOG_AUTH), as shutdown(8) and init(8) already do.

* nextboot: Smarter warning about deleting nextbootWarner Losh2025-01-141-1/+16
| | | | | | | | | | | | | | | | | | | | | | Read only filesystems always error when trying to remove something with EROFS. However, that's true even if the file isn't there. The code assumed it would always get a ENOENT if the file wasn't there, but produced a gross message on read only systems. This message was harmless, but annoying. Instead, stat the file first and return if it's already not there. Some readings of POSIX require that the ENOENT error take precidence over the EROFS error. Linux made this change years ago, and we should too. POSIX.1-2024 isn't explicit, but does say for unlink() does say "[EROFS] The directory entry to be unlinked is part of a read-only file system" and "[ENOENT] A component of path does not name an existing file" implying that EROFS should only be returned for an existing file. FreeBSD doesn't implement this, so this workaround is necessary. Ideally, we'd fix this in the kernel in the future.

* reboot: Implement zfs supportWarner Losh2024-02-121-9/+49
| | | | | | | | | | | | | | | | | | Implement full support for ZFS -k support. For ZFS, we have to set a property that gets cleared by the boot loaeder for whether or not to process nextboot.conf. Do this using system("zfsbootcfg..." rather than coding the small subset of that program inline to avoid CDDL contamination of reboot and the complications of disabling CDDL and/or ZFS. The few bytes needed to implement reboot for systems with zfs is not worth saving for systems w/o ZFS. Only set nextboot_enable=YES for UFS filesystems. They are the only one that need that as the first line. Its presence on ZFS can cause the kernel to not be oneshot.
