No, the old Bacula rescue CD does not do a pivot-root. > > 2. The Bacula CD can't find a fs module to load.

The old Bacula rescue CD (as currently released) worked on RedHat/Fedora until FC5, where they changed something that made it fail. It didn't seem to work very well on other distros, mostly because I didn't have those distros available so could not try them. The old rescue CD is probably not worth trying to fix. There is a Knoppix version in the current CVS (and is also released) that *should* work, but I have never personally tried it. I believe that there is some documentation in the knoppix directory somewhere. I have a new rescue CD that I am working on, which is based on the mkcdrec code and which will be released in the near future -- it is actually ready for testing now, but not in a polished state. The best bet would be to wait until I officially release it. If you *really* want to be on the bleeding edge of this problem, send me a note off-list and I'll post the code so you can download it and try it. I have booted it under SuSE 10.1, and am told it also boots under Fedora FC5. It *should* boot under most other distros, but that remains to be seen. > > -- > > Regards, > > Faber Fedor > President > Linux New Jersey, Inc. > 908-320-0357 > 800-706-0701 > > http://www.linuxnj.com > > > > > ------------------------------------------------------------------------- > Using Tomcat but need to do more?
