After struggling with the shell for some time I have come up with the
following modifications for /etc/hdparm.conf and /etc/init.d/hdparm.sh
that were suggested by Tommi Komulainen <[EMAIL PROTECTED]>.
(Tommi Komulainen suggestions can be seen as bug report #87451.)
The following:
1) Does not uses /proc, which might not be available.
2) Can have comments in the configuration file.
3) A default config file is possible by commenting out every line. Thus
the Debian maintainer can ship a default script which will do noting
without the explicit intervention of the sysadmin.
4) The config file have 'undo' lines so that when entering single user
mode from a production runlevel the configurations for the HDs will be
undone.
5) When using
update-rc.d default 05
the script will not be run in single user mode.
6) CDROMs can be configured as well.
7) If desired the script can be further simplified by removing the
verification of the HD model and/or removing the identify option.
This changes might make it more sh, as opposed to bash, complaint,
although I am not sure whether it is not sh compliant as it is.

# /etc/hdparm.conf
#
# Configuration file for /etc/init.d/hdparm.sh
# format: when:drive:model:params
# where
# when Is either start or stop. Lines beginning with anything
# else will be ignored. start will be used when entering
# a runlevel and stop when leaving it. This way, all
# configurations will be undone after changing to single
# user mode.
# drive Is hda, hdb and so on.
# model Should be the same as obtained using
# /etc/init.d/hdparm identify $drive
# or * if you do not mind about verifying the drive.
# params Are the required params.
#
# Don't mind that hda model will not be verified.
#start:hda:*:-qu1
# But I want its configuration to be the same as before when
# changing to single user mode.
#stop:hda:*:-qu0
