Hi all,
I'm using a pretty recent version of the hotplug scripts on my debian
box, with kernel 2.6.1-mm* and I've run into a small gotcha.
Since I have /usr mounted seperately, the default.hotplug script (and
some others) which use the env command, barf on startup, since hotplug
is running before /usr is mounted.
Sure, I could just copy /usr/bin/env to /bin/env, but I think that
ignores the problem.
John

'set' bash builtin command could be used instead.

Can they be changed to use 'set' instead of 'env'?

IIRC this is what I did in my own patch.
Maybe next month I will find some time to rediff it against the latest
release.

Not as far as I can see, since 'set' doesn't provide the environment
variables possibly used for debugging the way 'env' does.
As the basic level, it's probably either a Debian oversite, or a LSB
oversite.

Frustrating.
I also have many occasions where /usr is mounted "later".

Yes, you're right.
The real problem is that anything which runs that early
should not depend on /usr content.

Perhaps this:
sh -c set
where any variables exported to the environment
will be inherited by 'sh' as a child process,
unless overridden by a .bashrc or some such.
(Beware rc files for root. Badness reigns there.)
