[Jailkit-dev] [bug #20071] /lib/tls removed from Debian (Testing), jailkit does not pick up on changes

[anonymous]

Follow-up Comment #3, bug #20071 (project jailkit):

Related to this, jk_cp does not correctly pick up changes to symlinks either. 
Curiously, what it says it's doing (creating a symlink to the new target) is
correct, it just doesn't actually do it.

In this example, ld-linux-x86-64.so.2 pointed to a version of ld.so from
debian jessie; I updated to debian stretch and now the link points to a bad
filename:


address@hidden:/var/www/clients/client3/web8# ls -l lib64
total 0
lrwxrwxrwx 1 root root 32 Jul 28  2016 ld-linux-x86-64.so.2 ->
/lib/x86_64-linux-gnu/ld-2.19.so
address@hidden:/var/www/clients/client3/web8# ls -l /lib64/ld-linux-x86-64.so.2 
   
                                                   
lrwxrwxrwx 1 root root 32 Jun 15  2017 /lib64/ld-linux-x86-64.so.2 ->
/lib/x86_64-linux-gnu/ld-2.24.so


I tried to force that symlink to update via jk_cp -f, and the command output
says it created the symlink correctly:


address@hidden:/var/www/clients/client3/web8# jk_cp -f -j `pwd`
/lib64/ld-linux-x86-64.so.2                                            
Creating symlink /var/www/clients/client3/web8/lib64/ld-linux-x86-64.so.2 to
/lib/x86_64-linux-gnu/ld-2.24.so
Copying /lib/x86_64-linux-gnu/ld-2.24.so to
/var/www/clients/client3/web8/lib/x86_64-linux-gnu/ld-2.24.so



However in fact it did not change the symlink at all, it still points to the
old (removed) target:


address@hidden:/var/www/clients/client3/web8# md5sum  
lib64/ld-linux-x86-64.so.2   
                                                   
md5sum: lib64/ld-linux-x86-64.so.2: No such file or directory
address@hidden:/var/www/clients/client3/web8# ls -l lib64/ld-linux-x86-64.so.2
lrwxrwxrwx 1 root root 32 Jul 28  2016 lib64/ld-linux-x86-64.so.2 ->

address@hidden:/var/www/clients/client3/web8# ls -l
