Hi,
I'm not sure if this is considered a problem but I noticed some spurious
error messages during boot. The source appears to be:
1. a USB media card reader is plugged in at boot
2. the device node exists regardless of whether a card is present (expected)
3. line 70 of 60-persistent-storage.rules (KERNEL!=sr*,
IMPORT{builtin}=blkid) attempts blkid on the device with no card present
4. the open() call in builtin_blkid() in udev-builtin-blkid.c fails
resulting in an error: /dev/sdd: No medium found message printed to stderr
Adding ATTR{removable}==1, ATTR{size}==0, GOTO=skip_blkid around the
rule seems to work in my case but I don't know if that is a good thing to
do in general.
For comparison, the rules that run blkid on CD drives (lines 62-67) do
check first to make sure a CD is inserted. (At least I think that's
what ENV{ID_CDROM_MEDIA_TRACK_COUNT_DATA}==?*
is doing.)
Some other discussions I came across related to the No medium found
message:
