Bug 400967 – >=sys-apps/openrc-0.9.8.1 sysfs service fails to start when /etc/mtab is missing

• Product: Gentoo Hosted Projects
• Status: RESOLVED FIXED

[Description Ben Kohler 2012-01-26 21:42:28 UTC]

The mount_cgroups function in /etc/init.d/sysfs from >=sys-apps/openrc-0.9.8.1 uses just "mount" rather than "mount -n", so it fails on new installs and other places where /etc/mtab doesn't exist yet.

Reproducible: Always

Steps to Reproduce:
1. emerge ">=sys-apps/openrc-0.9.8.1"
2. rm /etc/mtab
3. reboot
Actual Results:  
 * Mounting /sys ...
 * Mounting debug filesystem ...
 * Mounting cgroup filesystem
can't create lock file /etc/mtab~932: Read-only file system (use -n flag to override)
can't create lock file /etc/mtab~934: Read-only file system (use -n flag to override)
can't create lock file /etc/mtab~936: Read-only file system (use -n flag to override)
can't create lock file /etc/mtab~938: Read-only file system (use -n flag to override)
 * ERROR: sysfs failed to start
 * Mounting /dev ...
 * ERROR: cannot start udev as sysfs would not start

... quite a few things go nutso after this due to failed udev

Created attachment 300007 [details, diff]
patch to fix cgroups mount

Should apply against sys-apps/openrc-0.9.8.{1,2}
