# Revision 1.3 2007/07/19 12:57:00 Jan Tomasek <jan@tomasek.cz> |
| 7 |
|
|
# * rewrited to work with /proc/bc/<VEID>/resources instead of |
| 8 |
|
|
# /proc/user_beancounters, that simplified code and result |
| 9 |
|
|
# is also bit faster. |
| 10 |
|
|
# * added references to OpenVZ wiki |
| 11 |
|
|
# Revision 1.3.1 2008/05/13 01:26:00 Daniel Hahler <http://daniel.hahler.de/> |
| 12 |
|
|
# * Minor fixes |
| 13 |
|
|
# - "exit 0" in "config" block |
| 14 |
|
|
# - Use "echo ${str%% *}" in "suggest", instead of "vals=($str); echo ${vals[0]}" |
| 15 |
|

|
# Revision 1.3.2 2008/08/09 12:30:00 Christian Rubbert <crubbert@xrc.de> |
