Granted, modifying sysfs layout is not something for the faint-hearted,
and one really has to look closely to ensure you end up with a
consistent layout afterwards.
But let's see how things go; might well be that it turns out to be too
complex to consider. Can't tell yet.
I would suggest aiming for something like devptsfs without the
complication of /dev/ptmx.
That is a pseudo filesystem that has a control node and virtual block
devices that were created using that control node.
Also see android/binder/binderfs.c
Ah. Will have a look.
That is the cleanest solution I know and is not strictly limited to use
with containers so it can also gain greater traction. The interaction
with devtmpfs should be simply having devtmpfs create a mount point for
that filesystem.
This could be a new cleaner api for things like loopback devices.
I sent a patchset that implemented this last year.
Do you have a pointer/commit hash for this?
Cheers,
Hannes
