initscripts/sysfs.sh: mount configfs if present

2017-03-01T12:54:20+00:00

configfs is another kernel virtual file system that should be mounted
if configured, so if it's configured into the kernel, mount it. It is
used to configure e.g. USB gadget mode and devicetree overlays.

initscripts: populate-volatile: suppress read-only-rootfs warnings

2016-12-22T08:46:37+00:00

rm: can't remove '/etc/resolv.conf': Read-only file system
ln: /etc/resolv.conf: File exists

/etc/default/volatiles contains an entry:
l root root 0644 /etc/resolv.conf /var/run/resolv.conf

which causes populate-volatile.sh to execute the following in link_file():
  if [ -L \"$2\" ]; then
    [ \"\$(readlink -f \"$2\")\" != \"\$(readlink -f \"$1\")\" ] && { rm -f \"$2\"; ln -sf \"$1\" \"$2\"; };
  elif [ -d \"$2\" ]; then
    ...

At the time the image is created, /etc/resolv.conf is already a
symlink to /var/run/resolv.conf, but at boot time when
populate-volatiles.sh is run, /var/run/resolv.conf doesn't
exist, causing it to try to rm -f and ln -sf which of course
fails due to the read-only filesystem.

initscripts: populate-volatile: don't run commands in background

2016-12-22T08:46:36+00:00

If commands are run asynchronously they may be completed out of
order causing problems if later entries depend on earlier ones.

2016-12-13T22:47:26+00:00

This improves the config file parsing to permit blank lines and
comments following an entry or preceeded by whitespace.

initscripts: Check for logrotate in dmesg.sh

2016-08-23T16:44:05+00:00

Autodetect previously hardcoded logrotate location because it can be
installed in multiple places like /usr/bin/logrotate which is very
common besides /usr/sbin

initscripts: check if swapon/swapoff exists before executing them

2016-05-30T08:30:33+00:00

Not all built images contain swapon/swapoff, for instance, it is
configurable with or without them in busybox. So it'd better to check if
they exist or not before executing them.

Redirecting the potential errors to /dev/null is not good enough, which
might suppress the *real* errors.

initscripts: populate-volatiles.sh: add mount-bind feature

2016-02-13T08:27:17+00:00

Add ability to run "mount --bind" to populate-volatiles. Since several
programs use realpath to determine several full qualified file names,
there is no symlink to be resolved. So when speccing /run/lock - that's
the location - not /var/run/lock because of the program is smarter
than the operator/distributor.

See https://github.com/rehsack/meta-jens/blob/jethro/recipes-core/initscripts/initscripts/volatiles
for an example how to use the "b" feature.

initscripts/sysfs.sh: Mount devtmpfs on /dev/ if needed

2015-10-24T11:19:36+00:00

When booting from an initrd disk, or when the kernel config option
DEVTMPFS_MOUNT isn't provided, /dev/ will not be mounted at boot.

This small addition will check if /dev/ is "useful", and if not, will
mount devtmpfs if the kernel provides it.

With this change, it is possible to set an initscripts style image type
to "cpio.gz" and boot it as initrd. Without this change, the image won't
work properly because of the missing devices.

initscripts: Fix regression for requiring /bin/bash

2015-08-09T22:14:30+00:00

It is not possible to create a rootfs with only busybox + initscipts.
This is a result of a regression from commit
a4b53872a8a9a2743299acbff015f7f2750a69d6 (initscripts: add
/sbin/sushell for systemd service debug-shell).

The /sbin/sushell should just use /bin/sh else you end up with a
problem when creating the end image with a failed smart transaction
shown below:
