Re: schroot leaving sessions behind

Hi, I set up a basic schroot environment to run a couple of 32 bit
apps on my amd64 box. The problem is that when the program exits
schroot leaves all its session data behind, mount points and all (so
`mount` returns a hell of a lot of entries)

schroot is being called as follows
`ls -l myprogram`
    myprogram -> do_schroot
`cat do_schroot`
    exec schroot -p -c sid32 -q -- "`basename $0`" "$@"
So when I run `myprogram` schroot runs it for me in a 32bit env. My
question is, what should I change to make sure that schroot uses as
few sessions as possible and closes them when done?

<snip large amount of chroots>

I had a similar problem when I first switched to schroot from dchroot.
In my case it turned out to be a problem with the way was launching
the  program in the chroot.  I originally used wrapper scripts, which
for some reason didn't terminate when the program they had launched
terminated, and therefore kept the session open.

It may help if you could give us more information on what myprogram
does, and how it is launched, in the chroot?

In any case you could try
#schroot -e --all-sessions

to kill the existing processes.

mypgrogram is one of: skype, bibblepro (photo editor), firefox (to have
32bit flash). I am sure there are a few others.

Do you have any scripts in the chroot to start them?
Normally I close them down, but often I will just shut down the
computer, maybe that causes it?

Possible
If i use -e --all-sessions will that not kill a running program in
another schroot?


Yes meant to add that caveat. Maybe add something to a run level 0 and 6 that executes this on shutdown to clean up /var/lib/chroot.
