man iftab_helper (Administration système) - udev callout to parse /etc/iftab and name network devices
NAME
iftab_helper - udev callout to parse /etc/iftab and name network devices
SYNOPSIS
iftab_helper devicename name
DESCRIPTION
iftab_helper is normally called from a udev rule to provide the name for a detected network device. Udev can use this information to rename devices and thus provide consistent names for network devices.
USAGE
iftab_helper takes the name of a network device which it looks up in the /etc/iftab file, returning the name assigned to it. If no name is specifically assigned, it checks whether the same name has been assigned to a different device, and if so requests a new name be generated.
iftab_helper is not responsible for performing the actual renaming, that is instead performed by udev using a NAME rule. This replaces the functionality previously offered by ifrename(8) though note that iftab_helper does not support as wide a range of selectors for devices and files may need to be simplified.
