In .c or in shell?

in shell:
- yes, /proc (.e.g `grep envID /proc/self/status` should return non-zero envID)
- /etc/fstab, /etc/mtab - i.e. disk partitions.
- pids... it is not guaranteed to work in future, but currently
all VE pids have one property:
(getpid() & 1024) == 1024
- empty dmesg on bootup
- others...

all this except for /proc are not guaranteed to work in future.

Thanks,
Kirill
