Control: tag -1 moreinfo Hi Jeffrey, Jeffrey Sheinberg <jeff@bsrd.net> (28/12/2012): > Likewise, this bug is still occuring in wheezy, I used: > > debian-wheezy-DI-b4-amd64-CD-1.iso > > to make this determination. > > I am cc-ing debian-boot, in the hope that someone there will be motivated > to take some interest in fixing this bug. netcfg has the following finish-install script: ,---[ finish-install.d/97release-dhcp-lease ]--- | #!/bin/sh | | set -e | | pid=$(pidof udhcpc) || true | [ -n "$pid" ] && kill -USR2 $pid | | if [ "$(pidof dhclient || true)" ]; then | dhclient -r || true | dhclient -6 -r || true | fi `--- which seems to match what you proposed in #610553: | Solution - please send SIGUSR2 to the "udhcpc" process at end of | installation (menu items: finish up the installation, or abort the | installation). AFAICT, $(pidof udhcpc) works, and the script quoted above looks reasonable. From a quick strace, it looks like udhcpc is properly releasing the lease on SIGUSR2. Any chance you could catch a network trace during the end of installation, and one on normal shutdown? To make sure DHCPRELEASE happens properly, you could also compare to a network trace when calling “kill -USR2 $(pidof udhcpc)” from a console after you obtained a lease. Mraw, KiBi.
