[SOLVED]post_install() problem

I was adding an install script to bind to setup a custom zone file and add rndc key.
My understanding  of the post_install() script was that it wasn't run until all of the package has been installed.  The behavior I've experienced, however, doesn't seem to validate this.
I've tried to use several of the files installed by the package in the install script and I get random errors that the files don't exist....meaning that the post_install() script is running in a separate thread and the installation of the package files is not complete.
Has anyone else experienced this?

Re: [SOLVED]post_install() problem

That doesn't seem right at all, but until you post the error messages and preferably the PKGBUILD/install script you tried using, we really have no way of knowing...

Re: [SOLVED]post_install() problem

bind package should install /etc/named.conf and /usr/bin/rndc-confgen
my bind.install script...

post_install() {
  echo "change name server"
  sed -i 's/#name_servers/name_servers/g' /etc/resolvconf.conf
  resolvconf -u
  mkdir -p /var/log/named
  touch /var/log/named/named.log
  chown root:40 /var/log/named/named.log
  chmod 664 /var/log/named/named.log
  touch /var/log/named/update-debug.log
  chown root:40 /var/log/named/update-debug.log
  chmod 664 /var/log/named/update-debug.log
  touch /var/log/named/named-auth.info
  chown root:40 /var/log/named/named-auth.info
  chmod 664 /var/log/named/named-auth.info
# set rndc key in named.conf
  echo "set rndc key"
  rndc-confgen > /etc/rndc.conf
  secret=`cat /etc/rndc.conf | grep secret | grep "#" | cut -d \" -f2`
  sed -i 's/rndc-secret/${secret}/g' /etc/named.conf
}

here's installation messages....

Re: [SOLVED]post_install() problem

It's running on bind-tools, not bind. You need to define the install file in the right place.

Or do it differently, that install file is pretty horrible. Most of that should be done by systemd-tmpfiles

Re: [SOLVED]post_install() problem

thanks, didn't appreciate the nuances of install scripts with split packages.  Moved the install=bind.install directive into the package section for bind and that fixed the issue
