#1 [pkgsrc] libkver and pbulk

libkver is the utility of faking the result of uname -a, and it is nice to use CHROOT pkgsrc build
when the kernel and userland in chroot is different. The typical story is:
  1. install NetBSD current, say 10.99.4
  2. prepare chrooted environment with 9.3
    (I do not use sandbox, but use pax to openup binaries/*.xz)
  3. do pkgsrc build inside chroot for Release 9.3

Info from ryoon, Ryo Onodera:

This is my start point, really helpful, thank you

pbulk and chroot:

Following two are theoretically, independent
  1. chroot
  2. pbulk
But we usually employ both at the same time. Especially pbulk remove everything under /usr/pkg

libkver:

  • install (make package) libkver inside of chroot for pbulk
    cd /usr/pkgsrc/pkgtools/libkver ; 
    env PATH=/usr/pkg_bulk/bin:/usr/pkg_bulk/sbin:${PATH} bmake package-install
    
  • copy two files onto outside of chroot
    sudo -s
    mkdir -p /usr/pkg_bulk/sbin
    mkdir    /usr/pkg_bulk/lib
    cp -p /CHROOT/usr/pkg_bulk/sbin/kver      /usr/pkg_bulk/sbin
    cp -p /CHROOT/usr/pkg_bulk/lib/libkber.so /usr/pkg_bulk/lib
    
    without doing above, you may got
    /usr/pkg/lib/libkver.so not found
    
    (after you once run pbulk)

start chroot with kver:

prepare shell script to start chroot shell (kind of optional)
/usr/pkg_bulk/sbin/kver -r 9.3 /usr/sbin/chroot /CHROOT
In my case, I insist using zsh, so zsh has been installed in chroot also, and then
env SHELL=/usr/pkg_bulk/bin/zsh  /usr/pkg_bulk/sbin/kver -r 9.3 /usr/sbin/chroot /CHROOT
