[systemd-devel] changing the "mount --make-shared /" default

the moderator queue, I went ahead and joined up ]

Hi Lennart (and the rest of the systemd gang),

I was quite surprised by some behavior that I found today in Fedora 18,
which I think comes from systemd.  I was trying to play with mount
namespaces and was rather surprised to find that they didn't work as
expected. After some googling, I realized that Fedora makes / a shared
mount by default.  That appears to come from:

http://cgit.freedesktop.org/systemd/systemd/commit/?id=b3ac5f8cb98757416d8660023d6564a7c411f0a0

where you say:

Setups which prefer the default of "private" should undo this change
via invoking "mount --make-private /" or a similar command after boot.

I am not sure that I want the default to be "private", but if I did,
what is the proper, systemd-ish way to do so?

thanks,

jake
