Bug 189686 – baselayout-2.0.0_rc3-r1 vserver: "failed to open `/proc/cmdline'"

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Christian Affolter 2007-08-21 10:28:39 UTC]

The rc manager tries to read the /proc/cmdline file while booting a vserver. This results in the following boot error message:
failed to open `/proc/cmdline': No such file or directory

Reproducible: Always

Steps to Reproduce:
1. Install a vserver with the latest baselayout and the init-style set to gentoo
2. start the vserver

Actual Results:  
   Gentoo/Linux; http://www.gentoo.org/

Press I to enter interactive boot mode

 * /proc is already mounted, skipping
 * Using existing device nodes in /dev ...                                [ ok ]
 * failed to open `/proc/cmdline': No such file or directory
 * Checking all filesystems ...                                           [ ok ]
[...]

Expected Results:  
No error messages, during startup ;)

Either unhide the /proc/cmdline within a vserver (however a vserver shouldn't be interested within the kernel's boot command line) or apply the attached patch for rc.c

Only read /proc/cmdline if it exists

Try this one - if /proc/cmdline exists then we read it, otherwise we don't

I've comitted my patch anyway, as I'm pretty sure it works.

Thanks
