[Pkg-sysvinit-devel] Bug#390339: upgrade of initscripts fails when no tmpfs is mounted (sid)

[Petter Reinholdtsen]

[Ingo Juergensmann]
> Apparently initscripts assumes the existance of tmpfs:

Yes, it does, to mount /dev/shm/ during boot among other things, and
recently to mount /lib/init/rw/.  Is your kernel missing tmpfs
support?  If this is the case, do this patch work?  How is /dev/shm/
mounted on your system if tmpfs isn't supported?
