Bug#1025730: initramfs-tools-core: configure_networking timeout causes entire init script to die
Package: initramfs-tools-core
Version: 0.142
Severity: normal
configure_networking tries to source /run/net-*.conf files at the end of its
run. If the networking timed out, no files exist. If the shell is also dash,
the '.' operator failing to find any file to source causes the entire shell to
exit, regardless of 'set -e' or not.
Naturally, this causes problems since the calling init script is
unceremoniously killed off in the middle of execution. I'd prefer if the init
script continued running, so it has an opportunity to retry the networking or
take other actions.
(I've encountered a few circumstances where configure_networking times out
before the network and DHCP are functional after a power outage.)
Just a brief demonstration of the surprising-to-me(-and-of-course-documented)
behavior:
paul@haley ~ % cat repro.sh
#!/bin/sh
. /nonexistent
echo hello
paul@haley ~ % dash ./repro.sh
./repro.sh: 3: .: cannot open /nonexistent: No such file
paul@haley ~ % sh ./repro.sh
./repro.sh: 3: .: cannot open /nonexistent: No such file
paul@haley ~ % bash ./repro.sh
./repro.sh: line 3: /nonexistent: No such file or directory
hello
paul@haley ~ %
