No, it's the init system; look at /lib/rc/sh/init.sh:66: |
| 56 |
|
| 57 |
# By default VServer already has /proc mounted, but OpenVZ does not! |
| 58 |
# However, some of our users have an old proc image in /proc |
| 59 |
# NFC how they managed that, but the end result means we have to test if |
| 60 |
# /proc actually works or not. We do this by comparing two reads of |
| 61 |
# /proc/self/environ for which we have set the variable VAR to two |
| 62 |
# different values. If the comparison comes back equal, we know that |
| 63 |
# /proc is not working. |
| 64 |
mountproc=true |
| 65 |
f=/proc/self/environ |
| 66 |
if [ -e $f ]; then |
| 67 |
if [ "$(VAR=a cat $f)" = "$(VAR=b cat $f)" ]; then |
| 68 |
eerror "You have cruft in /proc that should be deleted" |
| 69 |
else |
| 70 |
einfo "/proc is already mounted, skipping" |
| 71 |
mountproc=false |
| 72 |
fi |
| 73 |
fi |
| 74 |
unset f |
| 75 |
|
| 76 |
if $mountproc; then |
| 77 |
procfs="proc" |
| 78 |
[ "$RC_UNAME" = "GNU/kFreeBSD" ] && proc="linprocfs" |
| 79 |
ebegin "Mounting /proc" |
| 80 |
if ! fstabinfo --mount /proc; then |
| 81 |
mount -n -t "$procfs" -o noexec,nosuid,nodev proc /proc |
| 82 |
fi |
| 83 |
eend $? |
| 84 |
fi |
| 85 |

Mistery solved :D |
