This also adds a /bin/bash shebang to functions. While not technically
necessary, this ensures that vim gives us the correct syntax highlight
file.

devtmpfs is not used.

/sys/class/block contains all of our block devices, including the
partitions of each parent block device, so directly check for the
existance of the dev file rather than looping.

use blkid to resolve a tag name to a block device.

This should properly handle all ugly characters in values,
omit settings any forbidden variable names and take care
of double-quoted values with spaces in them.
This should finally fix FS#23467, FS#22080 and FS#13900.

The kernel command line allows quoted strings with whitespace in them. Until now,
such parameters would crash /init and cause a kernel panic.
Move parsing into a function and use the 'set' builtin to split /proc/cmdline
into arguments.
Fixes FS#13900 and FS#22080.

This reverts commit 9ef825cedd8228957f9bdd8df7ae543afd7e0001.
The introduced change was inconsistent with the standard 'mount' behaviour and
caused lots of confusion among LVM users.
|
|
It seems ash follows symlinks with -b.
|
|
If a symlink such as /dev/disk/by-uuid/xxxxx is provided on the kernel cmdline,
resolve it and mount that device instead of the symlink. This prevents some
ugliness in the output of commands such as mount or df.

remove more eval hacks
|
|
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.

rootdev variable
This is nicer and more explicit than before, based on a patch by Benjamin Richter

mount handler (default_mount_handler)

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.

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.
