[Jailkit-users] new utility: jk_update

[Olivier Sessink]

Hi all,

after the discussion on how to keep a jail updated I created a new 
utility: jk_update

right now it is pretty simplistic. I have a jail with my binary 
/home/testjail/bin/blaat. If I change the real /bin/blaat and I run 
jk_update it works:

# jk_update -j /home/testjail/
removing outdated file /home/testjail/bin/blaat
copying/linking /bin/blaat to /home/testjail/bin/blaat

jk_update tests all files in '/bin/', '/lib/', '/usr/', and '/opt/'

jk_update will check if the binary on the real system is newer, and the 
binaries should be different.

the question is, what other options should jk_update get? I'm 
implementing a 'dry-run' option right now so you will see what will be 
done. But what else would be useful?

-skipping certain files?
-adding more directories to update?

please give some feedback. You can try the latest development version in 
cvs.

regards,
        Olivier
