Sheesh Mike, I wasn't arguing against it, I was dissing on Linux. But still, even with shared code, the shared libraries demand: ~/src/share/man/man3 % size /usr/lib/libc.so text data bss dec hex filename 509098 15104 78200 602402 93122 /usr/lib/libc.so .(15:41:45)(bright@kyle.wintelcom.net) ~/src/share/man/man3 % size /bin/ps text data bss dec hex filename 184333 9928 37456 231717 38925 /bin/ps I may be misinterpreting this output, but it looks like if you ever mod FreeBSD to allow for disallowing of overcommit you might not have fun in low memory situations because of the BSS and DATA requirements needed for libc. (?) Anyhow, I'm not really arguing for or against, just bringing up some amusing experiances some coworkers had to deal with when using Linux and dynamic /. I really don't have much of a problem with a dynamic / since we already have /stand. Although /stand might need some new programs added to compensate, or a counterpart that gets updated as part of the installworld target. -- -Alfred Perlstein - [bright@wintelcom.net|alfred@freebsd.org] "I have the heart of a child; I keep it in a jar on my desk."
