Package: netcfg
Version: 1.131+deb8u1
Severity: important
The version is based off the
http://ftp.nl.debian.org/debian/dists/jessie/main/installer-amd64/current/images/udeb.list
I am trying to initiate a full hands off installation of Jessie on a remote
server.
We use iPXE to pass boot information, and I use:
BOOTIF=${netX/mac}
to have iPXE pass the MAC of the boot interface to Jessie d-i. However
netcfg refuses to parse the MAC from /proc/cmdline even though I can see it
there.
Here is the output from /var/log/syslog (DEBCONF_DEBUG=5 is set)
(paraphrased because I'm typing this out by hand):
~ # grep BOOTIF /var/log/syslog
kernel: [0.00000] Command line: auto=true priority=critical url=
http://thebooting.dev2.internal/preseed interface=auto DEBCONF_DEBUG=5
BOOTIF=0c:c4:7a:8e:ad:4a
kernel: [0.00000] Kernel command line: auto=true priority=critical url=
http://thebooting.dev2.internal/preseed interface=auto DEBCONF_DEBUG=5
BOOTIF=0c:c4:7a:8e:ad:4a
netcfg[780]: INFO: Could not find valid BOOTIF= entry in /proc/cmdline
This is me checking /proc/cmdline:
~ # cat /proc/cmdline
auto=true priority=critical url=http://thebooting.dev2.internal/preseed
interface=auto DEBCONF_DEBUG=5 BOOTIF=0c:c4:7a:8e:ad:4a
I've tried to look at the source (master branch from git://
anonscm.debian.org/d-i/netcfg.git) to try and figure out what's wrong, but
I am not a C developer.
Line 644 seems to be confusing because it's comparing 'bootif_len' to 20
[(6 * 3 - 1) + 3]
But MAC addresses are 15 characters long (including the colons).
I am going to code my way around this using the preseed/early_command for
setting the interface. But it would be nice if this issue was resolved. Let
me know if you need more information.
The installer information is:
Debian GNU/Linux installer
8 (jessie) - installer build 20150422+deb8u3
Thanks.

thanks for the confirmation. I'll go ahead and close the bug.
