The objective is to get /, /usr, /var and any other directory path the user feels is needed mounted before udev starts. This is a continuation of the "udev now sucks" thread from a few months ago. I need to fsck / before I mount /usr, /var and everything else. This is because the mount point directories could be zombies that would be removed by fsck, thus invalidating the mount. We all hope that /usr and /var are not zombies, but fsck won't take my word for it. -- Regards, Dave [RLU #314465] ====================================================================== dwn...@ntlworld.com (David W Noon) ======================================================================
