.SH SYNOPSIS
.B nabu kernel status

.RI alpha | stable | mainline | lts
.SH DESCRIPTION
The nabu-core-meta package requires at least one Nabu kernel family and
recommends alpha for fresh installations. Stable, alpha, mainline and the
future LTS family may coexist for development. Each family upgrades in place,
so a normal single-family installation retains only that family's newest RPM.
.PP
The use command installs the requested family and records it as the preferred
canonical UKI target. The add command installs an additional development family
without changing the preference. Neither operation reboots the device.
The legacy branch, brunch and brucnh forms remain compatibility aliases.
.SH FILES
.I /etc/nabu/kernel.conf
stores the preferred family and is preserved as an RPM noreplace configuration.
