NAME

     btxld -- link editor for BTX clients

SYNOPSIS

     btxld [-qv] [-b file] [-E address] [-e address] [-f format] [-l file] [-o filename] [-P page] [-W page] file

DESCRIPTION

     The btxld utility binds the specified client executable together with a BTX loader program and the BTX kernel, and creates a composite object
     file suitable for loading during the boot process.

     The options are:

     -q      Quiet: inhibit warnings.

     -v      Verbose: display information about the files processed.

     -b file
	     Specify the BTX kernel to be bound with the client.

     -E address
	     Set the client entry point.

     -e address
	     Set the BTX loader entry point.

     -f format
	     Specify the output format, where format is one of 'bin', 'aout', or 'elf'.

     -l file
	     Specify the BTX loader to be bound with the client.

     -o filename
	     Name the output file.  The default is ``a.out''.

     -P page
	     Specify the first page of the client's segment to be marked 'present', where page may be 0 or 1.

     -W page
	     Specify the first page of the client's segment to be marked 'writable', where page may be 0, and should not exceed the number of
	     pages occupied by the combined .text and .data segments of the client image.

EXIT STATUS

     The btxld utility exits 0 on success, and >0 if an error occurs.

ZFSLOADER(8)						    BSD System Manager's Manual 					      ZFSLOADER(8)

NAME

     zfsloader -- kernel bootstrapping final stage

DESCRIPTION

     zfsloader is an extended variant of loader(8) with added support for booting from ZFS.  This document describes only differences from
     loader(8).

ZFS FEATURES

     zfsloader supports the following format for specifying ZFS filesystems which can be used wherever loader(8) refers to a device specification:

     zfs:pool/filesystem:

     where pool/filesystem is a ZFS filesystem name as described in zfs(8).

     If /etc/fstab does not have an entry for the root filesystem and vfs.root.mountfrom is not set, but currdev refers to a ZFS filesystem, then
     zfsloader will instruct kernel to use that filesystem as the root filesystem.

ZFS COMMAND EXTENSIONS

     lsdev [-v]
	     Lists ZFS pools in addition to disks and partitions.  Adding -v shows more ZFS pool details in a format that resembles zpool status
	     output.

     lszfs filesystem
	     A ZFS extended command that can be used to explore the ZFS filesystem hierarchy in a pool.  Lists the immediate children of the
	     filesystem.  The filesystem hierarchy is rooted at a filesystem with the same name as the pool.

FILES

     /boot/zfsloader  zfsloader itself.

EXAMPLES

     Set the default device used for loading a kernel from a ZFS filesystem:

	   set currdev=zfs:tank/ROOT/knowngood:
