Documentation for updateself 2.1.0. Versioned source.

BSD

Install Bash first if absent, using your usual administrative access:

Platform	Bash prerequisite	Application updates
FreeBSD	pkg install bash	pkg upgrade
OpenBSD	pkg_add bash	pkg_add -u
NetBSD with configured pkgin	pkgin install bash	pkgin refresh/upgrade

updateself --only system --dry-run
updateself --only system --ask
updateself --only system --base-install --ask

Native commands can use root, sudo or doas. Switching from root to another user requires sudo/runuser; user tools need a non-root target account.

Base patches

• Traditional FreeBSD: supported freebsd-update fetch/install; jails and non-GENERIC kernels are skipped for this path.
• FreeBSD pkgbase: the combined pkg transaction can update the OS, so it requires --base-install; without it the combined transaction is skipped.
• OpenBSD: supported syspatch binary base patches require --base-install.
• NetBSD: base OS upgrades are outside the implemented scope.

No release migration or reboot is initiated. Inspect native output for restart requirements. CI verifies native package installation/removal, not live base patching on every release/custom kernel.

OpenBSD archives must retain updateself-VERSION.tgz before installation. Manuals use PREFIX/man/man1 on OpenBSD/NetBSD and PREFIX/share/man/man1 on FreeBSD. See Installation, Packages and Releases and Platform Support.
