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: https://bbs.archlinux.org/viewtopic.php?id=190229 https://bugs.freedesktop.org/show_bug.cgi?id=86414 Thanks, Hans
