Btw., is there any KIO slave or application for > KDE with similar functionality? Unfortunately no, or no volunteer yet ;-p. Timebrowse has two parts, snapshot manager and nautilus add-on. Snapshot manater keep nilfs checkpoints and alter its to snapshots and mount its specified mount point. In later snapshots will be unmount and sparse or deleted. While, nautils add-on is completely independent from the manager. It tries to find nilfs checkpoint mount from /proc/mounts and list the checkpoint. So if you want KIO slave or something similar for KDE, you may be able to utilize the snapshot manager to implement the functionality you want. > My target usecase was: OS is so mis-configured it won't even boot.

If the problem is rather simple, like need to boot correct kernel in the file system in the log boot loader may help it. #and pray the log roll forward on boot time. Current grub2 nilfs module only tries to find kernel from latest log. However, implementation itself can specify any checkpoint. The problem is how to specify the checkpoint from standard grub2 interface. grub2 does not have any parapeter for file system module :(. regards, > > Regards, > -- > dexen deVries > > [[[↓][→]]] > > For example, if the first thing in the file is: > <?kzy irefvba="1.0" rapbqvat="ebg13"?> > an XML parser will recognize that the document is stored in the traditional > ROT13 encoding. > > (( Joe English, http://www.flightlab.com/~joe/sgml/faq-not.txt )) > -- > To unsubscribe from this list: send the line "unsubscribe linux-nilfs" in > the body of a message to majordomo@xxxxxxxxxxxxxxx > More majordomo info at http://vger.kernel.org/majordomo-info.html > > > -- Jiro SEKIBA <jir@xxxxxxxxxx> -- To unsubscribe from this list: send the line "unsubscribe linux-nilfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
