Remove stime backport. Remove static libgcc patch as upstream fixed it with BUSYBOX_DEFAULT_STATIC_LIBGCC which defauls to off. Remove date -k patch as it no longer applies. It's also pointless as busybox' hwclock utility can do the same thing. Remove ntpd patch as that seems to have been applied upstream. Add smalll patch fixing compilation with SELinux. Upstream commit 2496616b0a8d1c80cd1416b73a4847b59b9f969a renamed the variable without renaming it in the SELinux path. Refresh config and patches. Config refresh: Refresh commands, run after busybox is first built once: cd package/utils/busybox/config/ ../convert_menuconfig.pl ../../../../build_dir/target-mips_24kc_musl/busybox-default/busybox-1.33.0 cd .. ./convert_defaults.pl < ../../../build_dir/target-mips_24kc_musl/busybox-default/busybox-1.33.0/.config > Config-defaults.in Manual edits needed afterward: * Config-defaults.in: OpenWrt config symbol IPV6 logic applied to BUSYBOX_DEFAULT_FEATURE_IPV6 * Config-defaults.in: OpenWrt configTARGET_bcm53xx logic applied to BUSYBOX_DEFAULT_TRUNCATE (commit547f1ec
) * editors/Config.in: Add USE_GLIBC dependency to BUSYBOX_CONFIG_FEATURE_VI_REGEX_SEARCH (commitf141090
) * shell/Config.in : change at "Options common to all shells" the symbol SHELL_ASH --> BUSYBOX_CONFIG_SHELL_ASH (discussion in http://lists.openwrt.org/pipermail/openwrt-devel/2021-January/033140.html Apparently our script does not see the hidden option while prepending config options with "BUSYBOX_CONFIG_" which leads to a missed dependency when the options are later evaluated.) * Edit Config.in files by adding quotes to sourced items in config/Config.in, networking/Config.in and util-linux/Config.in (commit1da014f
) Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> [Added comments from Hannu Nyman to commit message] Signed-off-by: Rosen Penev <rosenp@gmail.com>

help

acpid listens to ACPI events coming either in textual form from

|
/proc/acpi/event (though it is marked deprecated it is still widely
|
|
used and _is_ a standard) or in binary form from specified evdevs
|
|
(just use /dev/input/event*).
|
|
|
|
It parses the event to retrieve ACTION and a possible PARAMETER.
|
|
It then spawns /etc/acpi/<ACTION>[/<PARAMETER>] either via run-parts
|
|
(if the resulting path is a directory) or directly as an executable.

N.B. acpid relies on run-parts so have the latter installed.

The switch_root utility is used from initramfs to select a new

pivot_root. (Stop reading here if you don't care why.)

Booting with initramfs extracts a gzipped cpio archive into rootfs

(which is a variant of ramfs/tmpfs). Because rootfs can't be moved

|
or unmounted*, pivot_root will not work from initramfs. Instead,

switch_root deletes everything out of rootfs (including itself),

|
does a mount --move that overmounts rootfs with the new root, and
|
|
then execs the specified init program.

* Because the Linux kernel uses rootfs internally as the starting
|
|
and ending point for searching through the kernel's doubly linked
|
|
list of active mount points. That's why.

Linux kernels >= 2.6.24 support unlimited loopback devices. They are
|
|
allocated for use when trying to use a loop device. The loop device
|
|
must however exist.
|
|
|
|
This feature lets mount to try to create next /dev/loopN device
|
|
if it does not find a free one.

Historically, Unix systems kept track of the currently mounted
|
|
partitions in the file "/etc/mtab". These days, the kernel exports
|
|
the list of currently mounted partitions in "/proc/mounts", rendering
|
|
the old mtab file obsolete. (In modern systems, /etc/mtab should be
|
|
a symlink to /proc/mounts.)
|
|
|
|
The only reason to have mount maintain an /etc/mtab file itself is if
|
|
your stripped-down embedded system does not have a /proc directory.
|
|
If you must use this, keep in mind it's inherently brittle (for
|
|
example a mount under chroot won't update it), can't handle modern
|
|
features like separate per-process filesystem namespaces, requires
|
|
that your /etc directory be writable, tends to get easily confused
|
|
by --bind or --move mounts, won't update if you rename a directory
|
|
that contains a mount point, and so on. (In brief: avoid.)
|
|
|
|
About the only reason to use this is if you've removed /proc from
|
|
your kernel.
