vacation(1) on Solnix vs Linux and the BSDs

On Solnix, vacation is the illumos /usr/bin/vacation. Run with no arguments it is an interactive installer that creates .vacation.msg and .forward. The reply interval is set with -t, which accepts s, m, h, d and w suffixes. FreeBSD ignores -t and uses -r, and OpenBSD has no -t.

The manual pages

What Solnix runs

A default Solnix system runs the illumos vacation at /usr/bin/vacation. /usr/ucb/vacation is also shipped, but the bundle does not describe it. The page is published in pkgs.solnix.illumos-world-man.

Differences

Compared withTopicWhat differs
all fourinteractive installerSolnix vacation with no arguments starts an installer. It creates .vacation.msg, opens VISUAL, EDITOR or vi(1), and creates .forward if there is none. If a .forward exists, it asks whether to remove it, which disables vacation. The BSD pages describe no installer: you edit .forward and run vacation -i yourself.

FreeBSD, OpenBSD, NetBSDreply interval optionSolnix sets the interval with -tN, default 1 week, with a suffix s, m, h, d or w. FreeBSD and OpenBSD use -r in days. FreeBSD documents -t as ignored, kept only for compatibility with Sun's vacation. NetBSD accepts both -r and -t, with the same suffixes as Solnix and days as the plain unit.

FreeBSD, OpenBSD, NetBSDwhere options goOn Solnix, -a, -e, -f, -j, -m, -s and -t are meant for the .forward line, not the command line. FreeBSD says -d, -i, -I, -l and -x belong only on the command line. FreeBSD says -r should only be used when the database is initialized.

FreeBSD, OpenBSD, NetBSD-I and -i initializationSolnix documents only -I. It clears the sender list, enables vacation, and bare vacation is the installer. FreeBSD and NetBSD accept -i and -I as equivalent. OpenBSD documents only -i. The Solnix synopsis has no -i.

FreeBSD, NetBSD-d meaningSolnix vacation has no -d. On FreeBSD, -d sends errors and debug messages to stderr instead of syslog. On NetBSD, -d turns on debugging and prints the reply on stdout without sending it.

FreeBSD, OpenBSD, NetBSD-l listingSolnix and FreeBSD have -l to list replied-to addresses with a time. Solnix lists replies since the last vacation -I. The OpenBSD and NetBSD pages document no -l.

FreeBSD, OpenBSD, NetBSDdatabase filesSolnix creates .vacation.pag and .vacation.dir. OpenBSD and NetBSD name .vacation.db. FreeBSD names .vacation.db or .vacation.{dir,pag}. -f means a base name on Solnix, a path relative to ~ on FreeBSD unless it starts with /, and a prefix with .db appended on NetBSD. OpenBSD has no -f.

FreeBSD, OpenBSD, NetBSD-j, -s, -m supportSolnix, FreeBSD and NetBSD document -j (skip the To:/Cc: check) and -s (reply address). OpenBSD has neither. Solnix -m takes a path relative to ~ and says it should be on the same partition as ~/.forward. FreeBSD allows an absolute path.

FreeBSD, OpenBSD, NetBSDsender filteringSolnix reads an optional .vacation.filter (or -e file) of domains and addresses, some negated with !. The first match decides, and no match means no reply. FreeBSD instead has -x, which reads an exclusion list from stdin. OpenBSD and NetBSD document neither.

FreeBSD, OpenBSD, NetBSDsuppression rulesSolnix documents no reply for To:/Cc: not matching, -REQUEST@ senders, Precedence bulk or junk, postmaster and Mailer-Daemon. FreeBSD, OpenBSD and NetBSD also skip Precedence: list and Auto-Submitted other than no. FreeBSD and OpenBSD also skip List-Id. The Solnix page does not say it checks these.

FreeBSD, NetBSDextra options not on SolnixFreeBSD adds -C (sendmail.cf path), -R (envelope sender), -U (no password-file lookup) and -z (null sender). NetBSD adds -F (extra From-source headers) and -T (extra To-source headers, flagged in BUGS for non-compliant MTAs). Solnix has none of these.

Standards

Writing portable scripts

  • Do not script the reply interval: -tN on Solnix, -r days on FreeBSD and OpenBSD, and -r or -t on NetBSD. FreeBSD ignores -t.
  • In .forward, keep to -a alias and the login name. Initialize the database per system: bare vacation or -I on Solnix, -i on the BSDs.
