Bug 52870 – /etc/init.d/clock fails if it's run in coLinux environment

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Sergey Starosek 2004-06-03 04:25:53 UTC]

when /etc/init.d/clock is executed during startup modprobe
complains about missing /dev/rtc and /dev/misc. Even if I remove clock from the default runlevel, it's still required by syslog-ng.

There's a check in clock script for UML (User Mode Linux I guess). Adding such check for coLinux would be nice. One may check for the presense of /dev/cobd*
for example.

My system is:
Portage 2.0.50-r7 (default-x86-1.4, gcc-3.2.3, glibc-2.3.2-r9, 2.4.26-co-0.6.1)

using /dev/cobd* is not a valid check

what does /proc/cpuinfo report ?
what about `uname -a` ?

Created attachment 41965 [details]
(uname -a; cat /proc/cpuinfo /proc/devices) output

[Comment 3 Sergey Starosek 2004-10-16 09:07:51 UTC]

Created attachment 41966 [details]
(uname -a; cat /proc/cpuinfo /proc/devices) output (coLinux mode)

[Comment 4 Sergey Starosek 2004-10-16 09:12:57 UTC]

As you can see the difference is only in device list and kernel version.
I don't remember exactly but seem it was me who modified include/linux/version.h
so you may not rely on that difference.

[Comment 5 Sergey Starosek 2004-10-16 09:19:21 UTC]

to be exact, I've added EXTRAVERSION = -co-0.6.1 to a topmost Makefile

[Comment 6 Sergey Starosek 2004-10-16 09:21:17 UTC]

see http://www.colinux.org/wiki/index.php/coLinuxFAQ#A19
for details

[Comment 7 SpanKY 2004-10-16 09:49:50 UTC]

ok, i'll use this as the check then:
grep -q '^117 cobd$' /proc/devices

[Comment 8 SpanKY 2004-10-16 09:54:04 UTC]

+       elif grep -q ' cobd$' /proc/devices
+       then
+               TBLURB="coLinux"
+               return 0


-       if [ "${CLOCK}" == "UML" ]
+       if [ "${CLOCK}" == "UML" ] || [ "${CLOCK}" == "coLinux" ]
