`kproplog(8)` on Solnix vs Linux and the BSDs

On Solnix, kproplog is the illumos /usr/sbin/kproplog, which prints the Kerberos principal update log. Its SYNOPSIS lists only -h and -e num, plus -v in the OPTIONS. Unlike FreeBSD, it has no -R option to reset the log.

The manual pages

Solnix: kproplog(8) from pkgs.solnix.illumos-world-man · illumos.org
FreeBSD: kproplog(8) 15.1-RELEASE

What Solnix runs

A default Solnix system runs the illumos kproplog at /usr/sbin/kproplog. No other variants are shipped. The page names /var/krb5/principal.ulog as the update log file.

Differences

Compared with	Topic	What differs
FreeBSD	`-R` reset option	FreeBSD kproplog `-R` resets the update log and forces full resynchronization. If run on the primary, all replicas request full resyncs. The Solnix page documents no `-R`, so a script using it will fail on Solnix. Source: FreeBSD kproplog(8) SYNOPSIS, OPTIONS -R; Solnix kproplog(8) SYNOPSIS, OPTIONS
FreeBSD	synopsis and `-v`	The Solnix SYNOPSIS shows only [`-h` \| `-e` num], yet OPTIONS documents `-v`. The FreeBSD SYNOPSIS allows `-h`, `-e` num and `-v` together. The Solnix page does not say whether `-v` can be combined with the other options. Source: Solnix kproplog(8) SYNOPSIS, OPTIONS -v; FreeBSD kproplog(8) SYNOPSIS
FreeBSD	privilege needed	Solnix says kproplog can only be run on a KDC server by someone with privileges comparable to the superuser. FreeBSD says it requires read access to the update log file. Source: Solnix kproplog(8) DESCRIPTION; FreeBSD kproplog(8) DESCRIPTION
FreeBSD	log file location	Solnix names `/var/krb5/principal.ulog` as the update log file. The FreeBSD page does not give a path in the bundle text. Source: Solnix kproplog(8) DESCRIPTION; FreeBSD kproplog(8) DESCRIPTION
FreeBSD	terminology	Solnix uses master and slave KDC. FreeBSD uses primary and replica. The behaviour described is the same: with no options, the primary shows a summary plus all entries, and a replica shows only a summary. Source: Solnix kproplog(8) DESCRIPTION; FreeBSD kproplog(8) DESCRIPTION
FreeBSD	ENVIRONMENT section	FreeBSD refers to kerberos for Kerberos environment variables. The Solnix page has no ENVIRONMENT section. Source: FreeBSD kproplog(8) ENVIRONMENT; Solnix kproplog(8) (no ENVIRONMENT section)
Linux, OpenBSD, NetBSD	no counterpart page	The bundle has no Linux, OpenBSD or NetBSD kproplog page, so nothing can be said about how those systems differ. Source: Bundle header: only a freebsd COUNTERPART is listed

Standards

POSIX: kproplog is not a POSIX.1-2024 utility.
Solnix: Interface Stability: Evolving.

Writing portable scripts

Do not use kproplog -R in scripts meant for both systems: only FreeBSD documents it.
Use -h, -e num and -v as separate invocations, since the Solnix SYNOPSIS does not show them together.

Every difference here is taken from the manual pages linked above: Solnix's published page, Linux (man-pages and the GNU and util-linux manuals), FreeBSD, OpenBSD and NetBSD.
