[Pkg-sysvinit-devel] How is user-mode-linux using /dev/shm/?

[Petter Reinholdtsen]

Hi

I am one of the sysvinit maintainers.  Recently we changed the mount
options of /dev/shm/, and got a bug report about uml refusing to start
(#386945).  Because of this, I am curious how uml uses /dev/shm/.  Is
it using the shm-functions in glibc, or something else?  Please
explain how it work.

To make some writable tmpfs available to those in need of such system,
and to avoid using /dev/shm/ which is reserved for the shm-functions,
I just uploaded sysvinit version 2.86.ds1-26.  It will mount a tmpfs
on /lib/init/rw/ that can be used instead.  If /lib/init/rw/.ramfs
exist, that mount point is a tmpfs.  I'm not sure if this last change
will make it into Etch or not, but I hope so, to solve any problems
with packages previously using /dev/shm/ as a generic tmpfs file
system.

Friendly,
