Package: hdparm
Version: 9.15-1
Severity: normal
Tags: patch
README.Debian states that:
If you have devices that consistently come up in different orders (e.g.,
today's /dev/sda is tomorrow's /dev/sdb), then you can do one of two
things. Either you can directly use one of the various /dev/disk/by-*
symlinks, or you can create a udev rule to create a symlink to your
drive with a more friendly name. Then point hdparm at these symlinks
as you previously did with /dev/sda.
... but this didn't seem to work for me - hdparm never attempted to set
parameters for these devices. The init script did a string comparison
between each entry in hdparm.conf and the device name (e.g. "/dev/sdc"
etc.), as passed in by udev using the "DEVNAME" env variable.
The attached patch canonicalises the device name from hdparm.conf before
doing the comparison, and seems to work for me.
Ta,
Tim.
