iso.1 target and release(8) in RELENG_7 (WAS: Re: release(8) environmental variables)

[Brian A. Seklecki]

Here's some fun -- I'm pretty sure this worked in RELENG_6:

"make release" in /usr/src/release into RELEASEDIR=/opt/releasedir

The rebuild completes (release.1 -> release.8), the kernels are built,
the file system layout is prepared (ftp.1 -> cdrom.3), then (I think)
the iso.1 target is called and the images are zero-bytes.  Log excerpts
below...

Either I'm confused, I have my environmental variables set wrong, or
this is broken. :)

1) My $LOCAL_SCRIPT properly copies mkisofs(1) and mkhybrid(1) into
place in the $CHROOTDIR/usr/bin

   $ ls -al  /opt/relchroot/usr/bin/mkisofs
   -r-xr-xr-x  1 root  wheel  510712 Nov  1
            02:13 /opt/relchroot/usr/bin/mkisofs

2) On the root of the system, I have to make /R a sylink
   to /opt/relchroot/R to make "make iso.1" succeed :

   # ls -al /R 
    lrwxr-xr-x  1 root  wheel  16 Oct 29 23:20 /R -> /opt/relchroot/R


Other-wise:

 [root at build-fbsd-releng7-amd64 /usr/src/release]# make iso.1
   Creating ISO images...
   mkisofs: No such file or directory. Invalid node - /R/cdrom/bootonly
   *** Error code 2
   Stop in /usr/src/release.


3) I don't see how $CHROOTDIR is used in /usr/src/release/Makefile at:

   iso.1: 
   [...]

  Unless, when not run as a manual target outside of the chroot(), it
  runs in the chroot and /R is relative to $CHROOTDIR?.  That would make
  sense of the error in the log excerpt below matched what I encounter
  on the command line as a manual run.

I'm setting:

 # applies to build
 export DESTDIR=/opt/dest
 export MAKEOBJDIRPREFIX=/opt/obj
 export RELEASEDIR=/opt/release
 export CHROOTDIR=/opt/relchroot

This is a shell script that runs nightly -- it worked in RELENG_6.
