The dumpleases utility would be made more useful on a system with an SSD if
FEATURE_UDHCPD_WRITE_LEASES_EARLY were set at build time, because then you
wouldn't need to set a low auto_time (udhcpd.conf option) to get up-to-date
lease information from an unprivileged account, without having to first send
a signal to udhcpd from root. Please set this build option.

I guess it's still too much to write leases file on every DHCP ACK, even 6
years after this bug report has been submitted.

What would be useful though, is for dumpleases to send SIGUSR1 to dhcpd
before reading the leases file.  I guess.  Dunno how it would syncronize
though.
