2011-04-08Introduce /runThomas Bächler1-1/+2
Mount /run as a 10MB tmpfs with 1777 permissions early. Move it to /new_root when switching.
2011-04-08init: Unify/improve mount --move handlingThomas Bächler1-3/+7
- Loop over dev, sys, proc instead of repeating the same command. - If the target directory does not exist, umount instead of moving.

2010-12-06mount: forbid suid,exec,dev from /proc and /sysTom Gundersen1-2/+2
This is the counterpart to a similar patch to initscripts, making sure that the change applies regardless of whether initrd is used. Thanks to David Reisner for pointing out that this was needed.
2010-06-10Create /dev/{null,zero,mem,console} devices when devtmpfs is missingThomas Bächler1-0/+6
These devices used to be present because they were added in the image. Since we now mount {dev,}tmpfs early in initramfs, the devices from the image will be invisible. In the tmpfs-case, create the devices manually so everything will be in order until udev is started, or if udev isn't used at all.
2010-06-03Mount tmpfs or (if supported) devtmpfs on /dev, move it into the real root ↵Thomas Bächler1-0/+6
before switch_root
2010-06-03Do not umount /proc and /sys before switch_root, but mount --move them into ↵Thomas Bächler1-2/+2
the real root
2010-02-21poll_device: do not wait for a device to appear if udevd is not runningThomas Bächler1-0/+3
Devices will never "magically" appear when udevd is not running. Thus, poll_device now exits instantly when a device when udevd is not running. The return value is unchanged, just the delay is removed. Assuming that the drive is available just after loading the module is unsafe. However, "fast" devices like most (all?) pata/sata seem to work this way for many people. On "slow" devices like USB, we still have to wait - those will not work without udev.
2010-02-17Improve sanity check: ${init} must be executableThomas Bächler1-1/+1
2010-02-16When use stat -c %D instead of stat -f -c %i for testing if /new_root is a ↵Thomas Bächler1-1/+1
mount point The old check couldn't distinguish different tmpfs mounts and failed to work with aufs (archiso). This check is actually the same one that busybox/switch_root uses to determine where to stop deleting files. If this check fails and we still launch switch_root it may start deleting data.
2010-02-16Make indentation in two code blocks consistentThomas Bächler1-13/+13
2010-02-16Remove the special handling for the default mount procedure, move it into a ↵Thomas Bächler1-70/+3
mount handler (default_mount_handler)
2010-02-16Introduce mount handlersThomas Bächler1-9/+5
Instead of having special NFS code in /init, make it possible for a hook to register a mount handler When a hook sets the mount_handler environment variable, the normal mount code will be skipped and the handler will be called with the path to mount point as the first and only argument.
2010-02-15Do not kill -9 udevd, instead kill -15 and wait for all processes to ↵Thomas Bächler1-2/+4
terminate before continuing
2010-02-15If we could not mount the real root device, or the init program did not ↵Thomas Bächler1-1/+18
exist on it, bail out instead of panicing In these cases, we will exec /bin/sh, such that manual recovery is still possible as sh has PID 1 An expert might be able to mount and switch_root manually. In any case, this is less scary than a panic and a useless trace.
2010-02-14Kill udev after mounting file systems, not beforeThomas Bächler1-9/+10
Slow devices like USB devices will be detected after we kill udev, thus booting will fail. Kill udev as the last step, directly before we umount /proc and /sys and run switch_root.

There is no nss library or user/group database in initramfs, so tell udev to not try to resolve any names

2009-09-30rootdelay check: Fix compatibility with other sh implementations than dash ↵Thomas Bächler1-1/+1
and make it more reliable The old implementation failed on bash and failed on both if rootdelay was not a number. The logic is now as follows: If "$rootdelay"="", then [ -z "${rootdelay}" ] is true If not, then the part after the || is executed - if ${rootdelay} is not a number, or is <0, then [ ${rootdelay} -ge 0 ] fails, and the test will return true due to the !. The previous implementation failed here, because [ ! ${rootdelay} -ge 0 ] returns false on error, while ! [ ${rootdelay} -ge 0 ] returns true on error.

2009-06-07Don't only check for block devices, but also for symbolic links.Thomas Bächler1-1/+1
If we have a symlink, we don't check further if it points to a block device, partially due to klibc's readlink being broken.
2009-06-07Fix an 'elif' that should have been an 'if'Thomas Bächler1-1/+1
2009-06-06Rework the root device detection / creation stageThomas Bächler1-36/+34
- Set rootdelay to 10 by default - Skip the whole detection stage if we use root on nfs - Use the new poll_device function to wait for at most $rootdelay seconds - Always pass rootdelay=0 to kinit, as we ensure the existence of the root device - Don't reboot after the fallback. This allows a user to fix a problem and continue booting - Rely on kinit to detect the root filesystem type. The rootfstype= option can still be used to override Our old method would have failed as well, as the code for filesystem detection is the same
