skeleton: fix absence of /dev/shm on static, read-only systems

2015-10-03T13:34:28+00:00

/dev/shm is needed for systems using shared memory. On init-based systems this directory is usually created in the inittab along with /dev/pts, by the lines: package/busybox/inittab: ::sysinit:/bin/mkdir -p /dev/pts ::sysinit:/bin/mkdir -p /dev/shm package/sysvinit/inittab: si2::sysinit:/bin/mkdir -p /dev/pts si3::sysinit:/bin/mkdir -p /dev/shm However this is broken when static /dev management is selected and the root filesystem is read-only, showing during boot the error: mkdir: can't create directory '/dev/shm': Read-only file system Fix it by creating the empty /dev/shm directory, just like /dev/pts.

New top-level directory: system

2012-11-04T11:51:08+00:00

This directory groups the following elements: * the default root filesystem skeleton * the default device tables * the Config.in options for system configuration (UART port for getty, system hostname, etc.) * the make rules to apply the system configuration options Even though the skeleton and device tables could have lived in fs/, it would have been strange to have the UART, system hostname and other related options into fs/. A new system/ directory makes more sense. As a consequence, this patch also removes target/Makefile.in, which has become useless in the process.
