[fff2024g]

Dear all:
FreeBSD-15.0-RELEASE-amd64-disc1.iso don't have kernal.txz and base.txz ... i am wonder how to install freebsd15 to disk ?
if i want to install freebsd15.0 from console , not using bsdinstall tools in console . how to install freebsd15 step by step ? thanks.

note: i know how to install freebsd14 from console and not using bsdinstall tools . (we can extract kernal.txz and base.txz , but FreeBSD-15.0-RELEASE-amd64-disc1.iso don't have those files. so i don't know what is the step . thanks.)

The 15*disc1.iso comes with a set of pkgbase packages, the new systems kernel and base can be installed from these packages:

After you have absolved all necessary steps to receive the kernel and base files, install packages as follows (assuming the new file system is mounted on /mnt):

# cd /usr/freebsd-packages/offline

#  pkg  -r  /mnt  add `pwd`/FreeBSD-kernel-generic*
#  pkg  -r  /mnt  add `pwd`/FreeBSD-set-base*
#  pkg  -r  /mnt  add `pwd`/pkg-*

Alternatively, less to type

# pkg  -r  /mnt  -R   /usr/freebsd-packages/repos  install  Freebsd-kernel-generic  Freebsd-set-base  pkg

See pkg(8) for options description.

If you don't want pkgbase, you can fetch those distfiles from https://download.freebsd.org/releases/amd64/15.0-RELEASE/.
