Is this documented anywhere in relation to the current release?
Your link

got me searching for some of its key terms (linux drivetemp hwmon) which led to
https://www.kernel.org/doc/html/latest/hwmon/drivetemp.html
which says:
"[...] This driver supports reporting the temperature of disk and solid state drives with temperature sensors.
If supported, it uses the ATA SCT Command Transport feature to read the current drive temperature and, if available, temperature limits as well as historic minimum and maximum temperatures. If SCT Command Transport is not supported, the driver uses SMART attributes to read the drive temperature.
[...]
Sysfs entries
Only the temp1_input attribute is always available. Other attributes are available only if reported by the drive. All temperatures are reported in milli-degrees Celsius.
---------------------------------------
temp1_input | Current drive temperature
---------------------------------------
[...]"
There are various temp1_input files under /sys/... and it wasn't immediately clear where to look.
After some failed experimentation and a web search, I found
https://unix.stackexchange.com/questions/558112/standard-way-to-check-the-hard-drive-temperature-without-installing-additional-p
which suggests (as adapted for my machine)
$ cat /sys/class/scsi_disk/1:0:0:0/device/hwmon/hwmon3/temp1_input
35000
which matches (at different magnitude)
$ sudo smartctl -a /dev/sda |grep -i tem
194 Temperature_Celsius 0x0022 065 039 000 Old_age Always - 35 (Min/Max 11/61)
...which seems like a lot of effort to discover something that should (shouldn't it?) be documented somewhere in relation to Bookworm? I couldn't find anything in the release notes except some "notable" obsolete packages at s5.3, which didn't include hddtemp.
https://www.debian.org/releases/bookworm/amd64/release-notes/ch-information.en.html#noteworthy-obsolete-packages
Just out of interest, is there an authoritative list of packages removed per Debian version? The Bookworm release announcement says 'over 6,296 packages have been removed as "obsolete"'
https://www.debian.org/News/2023/20230610
I tried searching with both google and ddg and couldn't find anything authoritative looking.
That seems to invite a lot of detective work :)
Thanks,
Gareth
