Dynamic Root Support For FreeBSD Now Available

Posted by Hemos on from the coming-at-you dept.

Dan writes "FreeBSD's Gordon Tetlow has committed his enhancements to enable users to build /bin and /sbin dynamically linked on FreeBSD. His reason to do this is two-fold. One is to give better support for PAM and NSS in the base system. The second is to save some disk space. Currently (on his x86 box), /bin and /sbin are 32 MB. With a dynamically linked root (and some pruning of some binaries), the /bin, /lib, and /sbin come out to 6.1 MB. This should be great for people with 2.x and 3.x era root partitions that are only about 50 MB. Gordon says that there will be a performance hit associated with this. He did a quick measurement at boot and his boot time (from invocation of /etc/rc to the login prompt) went from 12 seconds with a static root to 15 seconds with a dynamic root."

    not only will this affect performance, but it will also make it impossible to recover a server if you accidentally delete /usr,

    there are less and less reasons to use seperate partitions for root directories, and this is *NOT GOOD*
