ok, i think i found the reason:

we're monitoring our servers using the nagios nrpe server.

nagios-nrpe-server.preinst on debian lenny adds the nagios user via:
> adduser --system --group --no-create-home --home /var/log/nagios --quiet nagios

but this directory does not exist:

> # ls -ald /var/log/nagios
> ls: cannot access /var/log/nagios: No such file or directory
> # su - nagios
> No directory, logging in with HOME=/

we then use "sudo crm ..." to monitor the cluster and it's node, so
crm will re-build the index in $HOME which is /

changing nagios' homedir or creating /var/log/nagios fixes this issue.
.crm_help_index is then created inside this user's $HOME.

thanks for your advice and the valuable input.

would it be reasonable to use /tmp or /var/tmp in case that $HOME
resolves to / or in case that $HOME isn't writable by this user?
(or not create the .crm_help_index at all)
