[Pkg-sysvinit-devel] Bug#644572: sysvinit: Spins disk up briefly from standby during poweroff

[Touko Korpela]

Package: sysvinit
Version: 2.88dsf-13.1
Severity: normal

I have system that mainly runs from SSD. Hard disk partitions are mounted
only when needed and disks are put to standby automatically after idle time.
However even when no HDD filesystems are mounted (and disk is spun down), during
shutdown sequence (when power button is pressed) the disk spins up briefly,
only to spin down instantly. It causes unneeded wear to disk mechanics.
I suspect that "-h" option that "halt" gets during poweroff is buggy and
shouldn't spin disks up that are already at sleep.
I'm not 100% sure that this bug belongs to halt, some more debugging (by me
if I find extra time) or somebody else is needed.
