Hello everyone, Mounting a COW filesystem -------------------------
A conventional filesystem file can be mounted, edited and unmounted between UML bootings that use it without problems. I mean something like that: mount root_fs /mnt/uml -o loop vi /mnt/uml/etc/hosts (or whatever) ... umount /mnt/uml I wonder if something similar could be done with COW-ed filesystems (created by a UML booting or with the uml_mkcow utility). As described in http://user-mode-linux.sourceforge.net/UserModeLinux-HOWTO-7.html, a COW-ed filesystems consists on two pieces: the backing filesystem (for example, root_fs) and the COW file with changes (for example, root_fs_cow). I've tried by mounting the COW file (mount root_fs_cow /mnt/uml -o loop), but it seems not working... :( Any idea? Getting filesystem differences as a COW file -------------------------------------------- Is possible to get the differences between two conventional filesystems (supposing both have the same size and block structure) as a COW file? Something like that: fs_diff root_fs_1 root_fs_2 > cow_fs Any comment/help related with this questions is really welcome! Thanks in advance!
