Guilmette [mailto:rfg@monkeys.com] Sent: Monday, October 18, 1999 8:59 PM To: freebsd-questions@freebsd.org Subject: Stupid file system tricks. Dumb question #1: Why can't I mount a single physical (ufs) file system in two different (logical) places at once? Dumb question #2: Given that I can't mount a (ufs) filesystem in two different places at once (perhaps because that would create some problem with synchronizing any writes to the filesystem and/or some problems with keeping in-core buffers always synched with what's on disk), why can't I at least mount a given filesystem *READ ONLY* in two different places at once? I tried it both ways, and either way, I just get: mount Device busy P.S. Please don't tell me to just use symlinks. Unless I'm mistaken, those may not work right if they point to a place outside of the specific directory tree that you have jsut chroot'ed to.
