Hi! *The following applies only if one uses eg. a USB stick to save the config* 1) "-h" .... print some help text and all possible command line options 2) "-b": When one runs "save-config -b" the old config will be backed upt to etc-backup.tar.bz2 3) option "-t timeout": When one runs "save-config -t 10" the config will be saved as etc-tryout.tar.bz2 instead of etc.tar.bz2 and the timeout value 10 will be written to a file named "try-out". At the next boot the system will detect both files from above, will load the etc-tryout.tar.bz2 and continue starting the system. Before the first prompt is displayed a "shutdown -r XX &", where XX is the value given via -t to save-config. Background: This way one could try out invasive changes to the config even from remote without the risk of loosing the old config in case the new config is crap. 4) /etc/sysconfig/save-config with the following content: # # This config option, only applicable when used with an USB configuration # media, allows one to keep more than one copy of the configuration. This # might be of help when the configuration media goes bad so there is an # increased chance to recover the configuration from one of the additional # ones. # NR_COPIES="3" So that's it for now. What do you think? -- MfG / Regards Friedrich Lobenstock ____________________________________________________________________ Friedrich Lobenstock Linux Services Lobenstock URL: http://www.lsl.at/ Email: fl...@fl... ____________________________________________________________________ |

Hmmmm, like that. Of course one would have to have root login enabled, which I usually don't allow. Heiko |

Now if we could just use tftp to load the config... :-) -- Arnaud |
