Package: hdparm Version: 9.15-1 Hello,
/etc/udev/rules.d/z60_hdparm.rules -> /etc/udev/hdparm.rules calls /etc/init.d/hdparm, which, in turn, calls /bin/sync during its run. This is not a good idea: sync can block quite a long time, which then leads to notable delays (read: hours) in the processing of hotplug events. For example, try `dd if=/dev/zero of=/dev/some-large-bdev bs=64k' and while it runs plug-in a partitioned USB-Stick. The /dev/sdX node will appear, but the partitions, i.e. /dev/sdX1 will not appear until dd has finished, because the sync called from the hdparm script blocks until then. Thanks for your work & regards, Mario -- It is practically impossible to teach good programming style to students that have had prior exposure to BASIC: as potential programmers they are mentally mutilated beyond hope of regeneration. -- Dijkstra
