Quoting Dan Kegel (dank at kegel.com):

"intended", no.  expected, yes.  Recent lkml discussions suggest that the
proper fix for this will be to impelement a new library to sit between
/proc files (like /proc/uptime) and applications.  In a container, this
could read a lxc-profiled file instead of /proc/uptime.

Work on that has not yet started though.  In the past, using a fuse
filesystem which sits on top of /proc has been considered, and Daniel
even had a prototype of one for a few files.  Not sure if uptime was
one of them.
