Using Busybox as your Default Shell
-----------------------------------
If you have/bin/sh linked to busybox, you need to be aware of several
incompatibilities between busybox's applets and the standalone
counterparts. Since it is possible to configure busybox to not include
these applets or to prefer the standalone counterparts, OpenRC does not
attempt to support the busybox applets.
All of these apply to busybox 1.20.2, which is the current version of
busybox as of this writing.
1. The start-stop-daemon applet is not compatible with start-stop-daemon
in OpenRC. Please make sure CONFIG_START_STOP_DAEMON is not set to y in
the configuration file you use to build busybox.
2. The -O option for the mount applet does not support the [no]_netdev
options from util-linux for handling network file systems.
3. The umount applet does not support the -O option from util-linux.
4. The swapon applet does not support the -e option from util-linux.
5. the setfont applet does not support the -u option from kbd.
There is work to get most of these supported by busybox, so this file
will be updated as things change.
