won't change that; 'chkconfig --add' registers the script for SysV init
only and it works with '-'.  But '-' prevents the script from being
started without prior activation. Such an activation is something like

| chkconfig vserver-default on

IMO, it is not a good (and insecure) style when services are activating
themself (s!-!345! would be such an activation) for automatic startup

should happen upon reboot by your distribution; but util-vserver works
fine with dangling symlinks also

it is difficultly to diagnose this without more details; but I
suspect that a process did not terminate and was killed by the
external vwait. .209 will contains some more diagnostic for this
case

IPs should be cleaned up, but sometimes, it is complicated to complete
tasks when previous actions failed; please try if it still happens
with .209 (which should appear this weekend) and reopen the bug when
needed

Ok, the issue regarding "/var/lib/run/vservers.rev" was Mandrake-package-related, and was corrected in the "util-vserver-*-0.30.208-3mdk" release. Thanks Daniel and Herbert !

I noticed a few bugs when using util-vserver.208 (The Mandrake rpms found at http://www.13thfloor.at/vserver/s_rel26/v2.0/ ):

- /var/lib/run/vservers.rev is not created, so the vservers do not start : Manually creating this directory solves the problem.

- /etc/init.d/vserver-default cannot be added by "chkconfig --add" because the corresponding line in the script is contains "-" instead of "345". Replacing the "-" by "345" enables to use "chkconfig --add vserver-default" so the marked vservers start at boot.

- /var/lib/run/vservers.rev seems to never be cleaned of its symlinks. Multiple ctxID point to a given vserver... I worried about some symlinks not having a trailing "/", but it's only because i've deleted the corresponding vserver ;-)
# ls -l /var/lib/run/vservers.rev/
total 0
49152 -> /etc/vservers/filesv
49153 -> /etc/vservers/distcc1/
49154 -> /etc/vservers/filesv
49155 -> /etc/vservers/filesv

- When I stop a vserver on some hosts, I get this message :
# vserver foo stop
/usr/lib/util-vserver/vserver.stop: line 85:  9287 Killed "${NICE_CMD[@]}" ${USE_VNAMESPACE:+$_VNAMESPACE --enter "$S_CONTEXT" -- }
$_VCONTEXT $SILENT_OPT --migrate --chroot --xid "$S_CONTEXT" -- "${INITCMD_STOP[@]}"

- When stopping a vserver, in addition to the strange message cited just above, I noticed that the corresponding IP alias is still up and running, answering to pings, etc... Is it a correct behaviour ?
