Hello everyone. FreeBSD 5.2.1-RELEASE with GENERIC kernel. I've made my own mfsroot and put into /sbin all requred files, among them: mount, mount_cd9660, mdmfs, mount_mfs and mount_nullfs. System booting from CD, then mounting md0 and root FS image. But I have a problem with mount_nullfs: # mount /dev/md0 on / (ufs, local) devfs on /dev (devfs, local) /dev/acd0 on /Frenzy/cd (cd9660, local, read-only) /dev/md7.ugz on /Frenzy/fs (ufs, local, read-only) # mount_nullfs /Frenzy/fs/bin /bin mount_nullfs: Operation not supported by device # mount_nullfs /bin /Frenzy/fs/bin mount_nullfs: No such file or directory # mount_nullfs /Frenzy/cd/boot /boot mount_nullfs: Operation not supported by device # mount_nullfs /boot /Frenzy/cd/boot mount_nullfs: No such file or directory With mount_unionfs got the same trouble. Then I've compiled mount_wrapfs (tool like mount_nullfs) from 'FIST' project (http://www.cs.columbia.edu/~ezk/research/fist/) and tried to do the same operation. Directories mounted OK. But when I trying to access these directories wia 'ls' (echo works OK), I've got kernel panic or message "Debug: root vnode is locked" and kernel panic again. Any suggestions? -- Best regards, Mozhaisky Sergei (techniX) [ http://frenzy.org.ua/ ]
