Do you mean / on LVM? Personally, I don't trust busybox on full scale installs, or on anything that's not embedded. Busybox necessarily omits certain features to keep the size and simplicity down whereas boot utilities are too often written for GNU tools. > > On Sat, Dec 5, 2009 at 4:42 AM, Alan McKinnon <alan.mckin...@gmail.com> wrote: > > On Friday 04 December 2009 17:25:21 Alex Schuster wrote: > >> Xi Shen writes: > >> > when i boot my system, at the step "Wiping /tmp", it pops up an error > >> > message saying that the find command do not support the '-uid' option. > >> > in the error message, i also see the busybox mark. it looks like it > >> > used the wrong find command. > >> > >> Did you emerge busybox with the make-symlinks USE flag?
