[lxc-users] Missing /proc/self after lxc-attach ?

[Mateusz Korniak]

Hi !
I am facing problem that 
/proc/self
is missing after I enter container via lxc-attach. [1]

When I log in to same container via lxc-start -F console, everything looks OK.
[2]

Is it bug or feature? 

It reduces usability of lxc-attach as many apps like top  [3]  and dynamic 
linking via RPATH [4] are not working :(

Confirmed Ubuntu 14.04. [5].

TIA, regards,


[1]: After lxc-attach entry to container:
# ls -la /proc/self
ls: cannot read symbolic link /proc/self: No such file or directory
lrwxrwxrwx 1 root root 0 Feb 15 12:05 /proc/self


[2]: After login via lxc-start console:
# ls -la /proc/self
lrwxrwxrwx 1 root root 0 Feb 15 12:05 /proc/self -> 1476


[3]:
# top
Error, do this: mount -t proc proc /proc
