Config file: libblkid Reference Manual

Config file

Config file — config file to control paths and basic library behavior

Description

The standard location of the /etc/blkid.conf config file can be overridden by the environment variable BLKID_CONF. The following options control the libblkid library:

SEND_UEVENT=`yes\|not`	Sends uevent when /dev/disk/by-{label,uuid}/ symlink does not match with LABEL or UUID on the device. Default is "yes".
CACHE_FILE=`path`	Overrides the standard location of the cache file. This setting can be overridden by the environment variable BLKID_FILE. Default is /etc/blkid.tab.
EVALUATE=`method`	Defines LABEL and UUID evaluation method(s). Currently, the libblkid library supports "udev" and "scan" methods. More than one methods may be specified in a comma separated list. Default is "udev,scan". The "udev" method uses udev /dev/disk/by-* symlinks and the "scan" method scans all block devices from the /proc/partitions file.
