    Revision 1168 - (hide annotations) (download)
    Wed Dec 15 17:44:36 2010 UTC (13 years, 4 months ago) by niro
    Original Path: trunk/busybox-initscripts/rc/rc
    File size: 4384 byte(s) 
    -added rc_print() and rc_echo() functions and replaced all corresponding echos with them
-added bootsplash support and initialize splash
-mount.rc: record mdev as mounted - equivalent to udev
-mount.rc: added devtmpfs to NO_FS
-rc-config: added mdev to RC_EXCLUDE
-removed udev.rc, should be installed with udev itself
