#1 addjailsw kills any daemon processes running in the jail

[Aubrey]

The addjailsw command kills any daemon processes
running through the jail!
e.g. any (jailed) user's ssh sessions will get killed
when I add extra software for that user.
Or is this normal behaviour?

even worse in my case (SuSE linux 7.3, I'll try debian on
the weekend):
if jail is running for /home/test2 and I run addjailsw for
the same user, jail stops responding and a few seconds later
the *whole system* crashes (I have to hit reset)

is anybody still developing this?
Is there a solution? I need to run jail on a production
web-server...

I made a patch that will

a) skip overwriting the destination file if it has not changed
b) delete the old destination file before copying

This should fix the issues. It should be tested on non-linux platforms though,
unlink might fail on some platforms if the library is in use.

As a side note: a) is not necessary, however I added it because it probably
saves some memory when new programs can reuse the old library (since it
was not overwritten).

The patch is here:

To apply the patch, after installing jail, do:

cd /
patch -p0 < jail-conditional-overwrite.diff
