[PATCH 2/5] Add /sbin/reboot and /sbin/halt to s390 initrd.img (#571370)

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Necessary for reboot or halt support from rescue mode.  Since
linuxrc.s390 currently does everything on s390x, add in handlers for
reboot and halt modes.
