The script is run by the FAI installer itself. Part of the FAI
installation process is to run scripts in
faiserver:/srv/fai/config/scripts/(by default) if the name of the
script matches a defined class.
As usual, I figured it out a short time after asking this question. It
finally occured to me to check the rsyncd log on the server. It says
access is denied because the user is not allowed. The rsync module
(really just a directory) is configured to allow only root user to
access. But wouldn't the script be run by root? I still haven't figured
that out but just specifying in the rsync command that it should connect
to the rsync server as root seems to have solved the problem.
The change I made is something like this:
rsync --archive --delete faiserver::local/ /usr/local/
to
rsync --archive --delete root@faiserver::local/ /usr/local/
Too bad the rsync logs don't say what user name it was trying to connect
as. There may be some way for me to get an FAI script to tell me what
the effective user name is but I don't want to mess around with that.
Anyway, this explains all the symptoms. I could ssh as root to the
machine on which the install is running and run the script. But then it
would connect as root. But I don't know why it isn't root when run as
part of the FAI install.

Hi,
do you run the script with $ROOTCMD? Then I guess you have to drop the $ROOTCMD
inside the script and also copy the rsync pw file to somewhere inside /target.
Or handle everthing without the chroot.

Subject: Totally stumped: Cannot run rsync via ROOTCMD
I have been working on a problem on and off for weeks. I am trying to
run rsync via a ROOTCMD in a script. During an install, the rsync does
nothing. If I ssh to the machine during the install and run the script
manually, it works. It also works when run via fai softupdate after the
install. I've even cut/pasted the rsync command from the script, sshed
to the machine during the install,typed 'chroot /target', and pasted the
command into the ssh window. So I know the rsync command works if you
change root to /target. It's just that during an install, when run via
the fai installer, it does nothing. I'll cut/paste the whole script at
the end of this message but here is a list of some of the versions of
the command that I have tried:
1. ${ROOTCMD} rsync --archive --delete --numeric-ids --hard-links
--password-file=/usr/local/etc/rsyncd.key faiserver::local/ /usr/local/
2. ${ROOTCMD} /usr/bin/rsync --archive --delete --numeric-ids
--hard-links --password-file=/usr/local/etc/rsyncd.key faiserver::local/
/usr/local/
3. ${ROOTCMD} /usr/bin/rsync --progress --archive --delete --numeric-ids
--hard-links --password-file=/usr/local/etc/rsyncd.key faiserver::local/
/usr/local/ >> /root/install.log
4. ${ROOTCMD} bash -c "/usr/bin/rsync --progress --archive --delete
--numeric-ids --hard-links --password-file=/usr/local/etc/rsyncd.key
faiserver::local/ /usr/local/ >> /root/install.log"
Note: When the script fails during an install, /root/install.log is empty.
Here is the entire script:
#! /bin/bash
error=0 ; trap "error=$((error|1))" ERR
fcopy -B -m root,root,0600 /usr/local/etc/rsyncd.key
echo "Beginning rsync"
${ROOTCMD} bash -c "/usr/bin/rsync --progress --archive --delete
--numeric-ids --hard-links --password-file=/usr/local/etc/rsyncd.key
faiserver::local/ /usr/local/ >> /root/install.log"
exit $error
# EOF
